Buddhist concepts

Life and the world

Karma: Cause and Effect

Karma (from Sanskrit: action, work)^[18] is the force that drives Samsāra, the cycle of suffering and rebirth for each being. Good, skillful (Pāli: kusala) and bad, unskillful (Pāli: akusala) actions produce "seeds" in the mind which come to fruition either in this life or in a subsequent rebirth.^[19] The avoidance of unwholesome actions and the cultivation of positive actions is called Śīla (from Sanskrit: ethical conduct).

In Buddhism, Karma specifically refers to those actions (of body, speech, and mind) that spring from mental intent (cetana),^[20] and which bring about a consequence (or fruit, phala)^[21] or result (vipāka). Every time a person acts there is some quality of intention at the base of the mind and it is that quality rather than the outward appearance of the action that determines its effect.

In Theravada Buddhism there can be no divine salvation or forgiveness for one's Karma, since it is a purely impersonal process that is a part of the make up of the universe. Some Mahayana traditions however hold different views. For example, the texts of certain Sutras (such as the Lotus Sutra, the Angulimaliya Sutra and the Nirvana Sutra) claim that reciting or merely hearing their texts can expunge great swathes of negative Karma. Similarly, the Japanese Pure Land teacher Genshin taught that Buddha Amitabha has the power to destroy the Karma that would otherwise bind one in Saṃsāra.^[22][23]

Rebirth

Rebirth refers to a process whereby beings go through a succession of lifetimes as one of many possible forms of sentient life, each running from conception^[24] to death. It is important to note, however, that Buddhism rejects concepts of a permanent self or an unchanging, eternal soul, as it is called in Christianity or even Hinduism. As there ultimately is no such thing as a self (anatta) according to Buddhism, rebirth in subsequent existences must rather be understood as the continuation of a dynamic, ever-changing process of "dependent arising" (Pratītyasamutpāda) determined by the laws of cause and effect (Karma) rather than that of one being, "jumping" from one existence to the next.

Each rebirth takes place within one of five realms, according to Theravadins, or six according to other schools.^[25][26] These are further subdivided into 31 planes of existence:^[27]

1. Naraka beings: those who live in one of many Narakas (Hells)
2. Animals: sharing some space with humans, but considered another type of life
3. Preta: sometimes sharing some space with humans, but invisible to most people; an important variety is the hungry ghost^[28]
4. Human beings: one of the realms of rebirth in which attaining Nirvana is possible
5. Asuras: variously translated as lowly deities, demons, titans, antigods; not recognized by Theravada (Mahavihara) tradition as a separate realm.^[29]
6. Devas including Brahmas: variously translated as gods, deities, spirits, angels, or left untranslated

Rebirths in some of the higher heavens, known as the Śuddhāvāsa Worlds (Pure Abodes), can be attained only by anāgāmis (non-returners). Rebirths in the arupa-dhatu (formless realms) can be attained only by those who can meditate on the arupa-jhānas.

According to East Asian and Tibetan Buddhism, there is an intermediate state (Tib. Bardo) between one life and the next. The orthodox Theravada commentorial position rejects this; however there are passages in the Samyutta Nikaya of the Pali Canon (the collection of texts on which the Theravada tradition is based), that seem to lend support to the idea that the Buddha taught of an intermediate stage between one life and the next.^[30][31]

The Cycle of Saṃsāra

Sentient beings crave pleasure and are averse to pain from birth to death. In being controlled by these attitudes, they perpetuate the cycle of conditioned existence and suffering (Saṃsāra), and produce the causes and conditions of the next rebirth after death. Each rebirth repeats this process in an involuntary cycle, which Buddhists strive to end by eradicating these causes and conditions, applying the methods laid out by the Buddhists.

Suffering: causes and solution

The Four Noble Truths

According to the Pali Tipitaka, the Four Noble Truths were the first teaching of Gautama Buddha after attaining Nirvana.^[32] They are sometimes considered as containing the essence of the Buddha's teachings and are presented in the manner of a medical diagnosis and remedial prescription – a style common at that time:

1. Life as we know it ultimately is or leads to suffering/uneasiness (dukkha) in one way or another.
2. Suffering is caused by craving or attachments to worldly pleasures of all kinds. This is often expressed as a deluded clinging to a certain sense of existence, to selfhood, or to the things or phenomena that we consider the cause of happiness or unhappiness.
3. Suffering ends when craving ends, when one is freed from desire. This is achieved by eliminating all delusion, thereby reaching a liberated state of Enlightenment (bodhi);
4. Reaching this liberated state is achieved by following the path laid out by the Buddha.

Described by early Western scholars, and taught as an introduction to Buddhism by some contemporary Mahayana teachers (e.g., the Dalai Lama).^[33]

According to other interpretations by Buddhist teachers and scholars, lately recognized by some Western non-Buddhist scholars,^[34] the "truths" do not represent mere statements, but are categories or aspects that most worldly phenomena fall into, grouped in two:

1. Suffering and causes of suffering
2. Cessation and the paths towards liberation from suffering.

Thus, according to the Macmillan Encyclopedia of Buddhism^[35] they are

1. "The noble truth that is suffering"
2. "The noble truth that is the arising of suffering"
3. "The noble truth that is the end of suffering"
4. "The noble truth that is the way leading to the end of suffering"

The early teaching^[36] and the traditional Theravada understanding^[37] is that the Four Noble Truths are an advanced teaching for those who are ready for them. The Mahayana position is that they are a preliminary teaching for people not yet ready for the higher and more expansive Mahayana teachings.^[38] They are little known in the Far East.^[39]

The Noble Eightfold Path

The Noble Eightfold Path, the fourth of the Buddha's Noble Truths, is the way to the cessation of suffering (dukkha). It has eight sections, each starting with the word samyak (Sanskrit, meaning correctly, properly, or well,^[40] frequently translated into English as right), and presented in three groups (NB: Pāli transliterations appear in brackets after Sanskrit ones):

• Prajñā is the wisdom that purifies the mind, allowing it to attain spiritual insight into the true nature of all things. It includes:

1. dṛṣṭi (Pāli ditthi): viewing^[41] reality as it is, not just as it appears to be.
2. saṃkalpa (sankappa): intention^[42] of renunciation, freedom and harmlessness.

• Śīla is the ethics or morality, or abstention from unwholesome deeds. It includes:

1. vāc (vāca): speaking^[43] in a truthful and non-hurtful way
2. karman (kammanta): acting^[44] in a non-harmful way
3. ājīvana (ājīva): a non-harmful livelihood^[45]

• Samādhi is the mental discipline required to develop mastery over one’s own mind. This is done through the practice of various contemplative and meditative practices, and includes:

1. vyāyāma (vāyāma): making an effort^[46] to improve
2. smṛti (sati): awareness^[47] to see things for what they are with clear consciousness, being aware of the present reality within oneself, without any craving or aversion
3. samādhi (samādhi): correct meditation or concentration,^[48] explained as the first four dhyānas

The practice of the Eightfold Path is understood in two ways, as requiring either simultaneous development (all eight items practiced in parallel), or as a progressive series of stages through which the practitioner moves, the culmination of one leading to the beginning of another.

In the early sources (the four main Nikayas) the Eightfold Path is not generally taught to laypeople, and it is little known in the Far East.^[49]

Middle Way

An important guiding principle of Buddhist practice is the Middle Way, which is said to have been discovered by Gautama Buddha prior to his enlightenment (bodhi). The Middle Way or Middle Path has several definitions:

1. The practice of non-extremism: a path of moderation away from the extremes of self-indulgence and self-mortification
2. The middle ground between certain metaphysical views (e.g., that things ultimately either do or do not exist)^[50]
3. An explanation of Nirvana (perfect enlightenment), a state wherein it becomes clear that all dualities apparent in the world are delusory (see Seongcheol)
4. Another term for emptiness, the ultimate nature of all phenomena (in the Mahayana branch), lack of inherent existence, which avoids the extremes of permanence and nihilism or inherent existence and nothingness

The nature of reality

Buddhist scholars have produced a remarkable quantity of intellectual theories, philosophies and world view concepts (see, e.g., Abhidharma, Buddhist philosophy and Reality in Buddhism). Some schools of Buddhism discourage doctrinal study, some regard it as essential, but most regard it as having a place, at least for some people at some stages. The concept of Liberation (Nirvana), the goal of the Buddhist path, is closely related to the correct perception of reality. In awakening to the true nature of the self and all phenomena one is liberated from the cycle of suffering (Dukkha) and involuntary rebirths (Samsara).

Impermanence, suffering and non-self

Impermanence is one of the Three Marks of Existence. The term expresses the Buddhist notion that all compounded or conditioned phenomena (things and experiences) are inconstant, unsteady, and impermanent. Everything we can experience through our senses is made up of parts, and its existence is dependent on external conditions. Everything is in constant flux, and so conditions and the thing itself are constantly changing. Things are constantly coming into being, and ceasing to be. Nothing lasts.

According to the impermanence doctrine, human life embodies this flux in the aging process, the cycle of rebirth (samsara), and in any experience of loss. The doctrine further asserts that because things are impermanent, attachment to them is futile and leads to suffering (dukkha).

Suffering or Dukkha (Pāli दुक्ख; Sanskrit दुःख duḥkha; according to grammatical tradition derived from dus-kha "uneasy", but according to Monier-Williams more likely a Prakritized form of dus-stha "unsteady, disquieted") is a central concept in Buddhism, the word roughly corresponding to a number of terms in English including suffering, pain, unsatisfactoriness, sorrow, affliction, anxiety, dissatisfaction, discomfort, anguish, stress, misery, and frustration.

Although dukkha is often translated as "suffering", its philosophical meaning is more analogous to "disquietude" as in the condition of being disturbed. As such, "suffering" is too narrow a translation with "negative emotional connotations" (Jeffrey Po),^[51] which can give the impression that the Buddhist view is one of pessimism, but Buddhism is neither pessimistic nor optimistic, but realistic. Thus in English-language Buddhist literature dukkha is often left untranslated, so as to encompass its full range of meaning.^[52][53][54]

Anatta (Pāli) or anātman (Sanskrit) refers to the notion of "not-self". In Indian philosophy, the concept of a self is called ātman (that is, "soul" or metaphysical self), which refers to an unchanging, permanent essence conceived by virtue of existence. This concept and the related concept of Brahman, the Vedantic monistic ideal, which was regarded as an ultimate ātman for all beings, were indispensable for Brahminical metaphysics, logic, and science; for all apparent things there had to be an underlying and persistent reality, akin to a Platonic form. Buddhists reject all these concepts of ātman, emphasizing not permanence, but changeability. Therefore all concepts of a substantial Self are incorrect and formed in the realm of ignorance.

In the Nikayas, anatta is not meant as a metaphysical assertion, but as an approach for gaining release from suffering. In fact, the Buddha rejected both of the metaphysical assertions "I have a Self" and "I have no Self" as ontological views that bind one to suffering.^[55] By analyzing the constantly changing physical and mental constituents (skandhas) of a person or object, the practitioner comes to the conclusion that neither the respective parts nor the person as a whole comprise a Self.

Dependent arising

The doctrine of pratītyasamutpāda (Sanskrit; Pali: paticcasamuppāda; Tibetan: rten.cing.'brel.bar.'byung.ba; Chinese: 緣起), often translated as "Dependent Arising," is an important part of Buddhist metaphysics. It states that phenomena arise together in a mutually interdependent web of cause and effect. It is variously rendered into English as "dependent origination", "conditioned genesis", "dependent co-arising", "interdependent arising", or "contingency".

The best-known application of the concept of Pratītyasamutpāda is the scheme of Twelve Nidānas (from Pāli nidāna "cause, foundation, source or origin"), which explain the continuation of the cycle of suffering and rebirth (Samsara) in detail.^[56]

The Twelve Nidānas describe a causal connection between the subsequent characteristics/conditions of cyclic existence, each giving rise to the next:

1. Avidyā: ignorance, specifically spiritual^[57]
2. Saṃskāras: literally formations, explained as referring to Karma.
3. Vijñāna: consciousness, specifically discriminative^[58]
4. Nāmarūpa: literally name and form, referring to mind and body^[59]
5. Ṣaḍāyatana: the six sense bases: eye, ear, nose, tongue, body and mind-organ
6. Sparśa: variously translated contact, impression, stimulation (by a sense object)
7. Vedanā: usually translated feeling: this is the "hedonic tone", i.e. whether something is pleasant, unpleasant or neutral
8. Tṛṣṇā: literally thirst, but in Buddhism nearly always used to mean craving
9. Upādāna: clinging or grasping; the word also means fuel, which feeds the continuing cycle of rebirth
10. Bhava: literally being (existence) or becoming. (The Theravada explains this as having two meanings: karma, which produces a new existence, and the existence itself.)^[60]
11. Jāti: literally birth, but life is understood as starting at conception^[61]
12. Jarāmaraṇa: (old age and death) and also śokaparidevaduḥkhadaurmanasyopāyāsa (sorrow, lamentation, pain, sadness, and misery)

Sentient beings always suffer throughout samsara, until they free themselves from this suffering by attaining Nirvana. Then the absence of the first Nidāna, ignorance, leads to the absence of the others.

Emptiness

Mahāyāna Buddhism received significant theoretical grounding from Nāgārjuna (perhaps c. 150–250 CE), arguably the most influential scholar within the Mahāyāna tradition. Nāgārjuna's primary contribution to Buddhist philosophy was the systematic exposition of the concept of śūnyatā, or "emptiness," widely attested in the Prajñāpāramitā sutras which were emergent in his era. The concept of emptiness brings together other key Buddhist doctrines, particularly anatta (no-self) and pratītyasamutpāda (dependent origination), to refute the metaphysics of Sarvastivada and Sautrantika (extinct non-Mahayana schools). For Nāgārjuna, as for the Buddha in the early texts, it is not merely sentient beings that are empty of ātman; all phenomena (dharmas) are without any svabhāva, literally "own-nature" or "self-nature", and thus without any underlying essence; they are empty of being independent; thus the heterodox theories of svabhava circulating at the time were refuted on the basis of the doctrines of early Buddhism. Nāgārjuna's school of thought is known as the Mādhyamaka. Some of the writings attributed to Nāgārjuna made explicit references to Mahāyāna texts, but his philosophy was argued within the parameters set out by the agamas. He may have arrived at his positions from a desire to achieve a consistent exegesis of the Buddha's doctrine as recorded in the Canon. In the eyes of Nāgārjuna the Buddha was not merely a forerunner, but the very founder of the Mādhyamaka system.^[62]

Sarvāstivāda teachings, which were criticized by Nāgārjuna, were reformulated by scholars such as Vasubandhu and Asaṅga and were adapted into the Yogācāra (Sanskrit: yoga practice) school. While the Mādhyamaka school held that asserting the existence or non-existence of any ultimately real thing was inappropriate, some exponents of Yogācāra asserted that the mind and only the mind is ultimately real (cittamatra). Not all Yogācārins asserted that mind was truly existent; Vasubandhu and Asanga in particular did not.^[63] These two schools of thought, in opposition or synthesis, form the basis of subsequent Mahāyāna metaphysics in the Indo-Tibetan tradition.

Besides emptiness (śūnyatā), Mahāyāna schools often place emphasis on the notions of perfected spiritual insight (prajñāpāramitā) and Buddha-nature (tathāgatagarbha). According to the tathāgatagarbha sutras, the Buddha revealed the reality of the deathless Buddha-nature (tathāgatagarbha - which means 'Buddha embryo' or 'Buddha-matrix'), which is said to be inherent in all sentient beings and enables them all eventually to reach complete enlightenment, i.e. Buddhahood. Buddha-nature is stated in the Mahāyāna Angulimaliya Sutra and Mahaparinirvana Sutra not to be śūnya, but to be replete with eternal Buddhic virtues. In the tathāgatagarbha sutras the Buddha is portrayed proclaiming that the teaching of the tathāgatagarbha constitutes the "absolutely final culmination" of his Dharma—the highest presentation of truth (other sūtras make similar statements about other teachings) and it has traditionally been regarded as the highest teaching in East Asian Buddhism. However, in modern China all doctrines are regarded as equally valid.^[64] The Mahāyāna can also on occasion communicate a vision of the Buddha or Dharma which amounts to mysticism and gives expression to a form of mentalist panentheism (God in Buddhism).

Speculation versus direct experience: Buddhist epistemology

Decisive in distinguishing Buddhism from other schools of Indian philosophy is the issue of epistemological justification (from epistemology, Greek: theory of knowledge). While all schools of Indian logic recognize various sets of valid justifications for knowledge, or pramana, Buddhism recognizes a smaller set than do the others. All accept perception and inference, for example, but for some schools of Buddhism the received textual tradition is an equally valid epistemological category.^[65]

According to the scriptures, during his lifetime the Buddha remained silent when asked several metaphysical questions. These regarded issues such as whether the universe is eternal or non-eternal (or whether it is finite or infinite), the unity or separation of the body and the self, the complete inexistence of a person after nirvana and death, and others. One explanation for this silence is that such questions distract from activity that is practical to realizing enlightenment^[66] and bring about the danger of substituting the experience of liberation by conceptual understanding of the doctrine or by religious faith.^[67] Another explanation is that both affirmative and negative positions regarding these questions are based on attachment to and misunderstanding of the aggregates and senses. That is, when one sees these things for what they are, the idea of forming positions on such metaphysical questions simply does not occur to one.^[68] Another closely related explanation is that reality is devoid of designations, or empty, and therefore language itself is a priori inadequate.^[69]

Thus, the Buddha's silence does not indicate misology or disdain for philosophy. Rather, it indicates that he viewed these questions as not leading to true knowledge.^[69] Dependent arising is, according to some^[who?], one of the Buddha's great contributions to philosophy, and provides a framework for analysis of reality that is not based on metaphysical assumptions regarding existence or non-existence, but instead on direct cognition of phenomena as they are presented to the mind. This informs and supports the Buddhist approach to liberation via ethical and meditative training known as the Noble Eightfold Path.

The Buddha of the earliest Buddhists texts describes Dharma (in the sense of truth) as "beyond reasoning", or "transcending logic", in the sense that reasoning is a subjectively introduced aspect of the way humans perceive things, and the conceptual framework which underpins it is a part of the cognitive process, rather than a feature of things as they really are. "Beyond reasoning" means in this context penetrating the nature of reasoning from the inside, and removing the causes for experiencing any future stress as a result of it, rather than functioning outside of the system as a whole.^[70]

Most Buddhists agree that, to a greater or lesser extent, words are inadequate to describe the goal of the Buddhist path, but concerning the usefulness of words in the path itself, schools differ radically.^[71]

In the Mahayana Mahaparinirvana Sutra, the Buddha insists that, while pondering upon Dharma is vital, one must then relinquish fixation on words and letters, as these are utterly divorced from liberation and the Buddha-nature. The tantra entitled the "All-Creating King" (Kunjed Gyalpo Tantra, a scripture of Tibetan Buddhism) also emphasizes how Buddhist truth lies beyond the range of discursive/verbal thought and is ultimately mysterious. The Supreme Buddha, Samantabhadra, states there: "The mind of perfect purity ... is beyond thinking and inexplicable ...."^[72] Also later, the famous Indian Buddhist practitioner (yogi) and teacher, mahasiddha Tilopa discouraged any intellectual activity in his six words of advice.

Professor C. D. Sebastian describes the nature of enlightenment according to one Mahayana text:

"Bodhi is the final goal of a Bodhisattva's career and it is indicated by such words as buddha-jnana (knowledge of Buddha), sarvjnata (omniscience), sarvakarajnata (the quality of knowing things as they are), ... and acintyam jnanam (inconceivable knowledge) ... Bodhi is pure universal and immediate knowledge, which extends over all time, all universes, all beings and elements, conditioned and unconditioned. It is absolute and identical with Reality and thus it is Tathata. Bodhi is immaculate and non-conceptual, and it, being not an outer object, cannot be understood by discursive thought. It has neither beginning, nor middle nor end and it is indivisbile. It is non-dual (advayam)... The only possible way to comprehend it is through samadhi by the yogin"^[73]

The early texts, in contrast, contain explicit repudiations of attributing omniscience to the Buddha.^[74][75] Furthermore, the non-duality ascribed to the nature of enlightenment in the early texts is not ontological.^[76]

Mahayana often adopts a pragmatic concept of truth:^[77] doctrines are "true" in the sense of being spiritually beneficial. In modern Chinese Buddhism, all doctrinal traditions are regarded as equally valid.^[64]

Theravāda promotes the concept of Vibhajjavada (Pāli), literally "Teaching of Analysis". This doctrine says that insight must come from the aspirant's experience, critical investigation, and reasoning instead of by blind faith. As the Buddha said according to the canonical scriptures:^[78]

Do not accept anything by mere tradition ... Do not accept anything just because it accords with your scriptures ... Do not accept anything merely because it agrees with your pre-conceived notions ... But when you know for yourselves—these things are moral, these things are blameless, these things are praised by the wise, these things, when performed and undertaken, conduce to well-being and happiness—then do you live acting accordingly.

Liberation

Nirvana

Nirvana (Sanskrit; Pali Nibbana) means "cessation", "extinction" (of craving and ignorance and therefore suffering and the cycle of involuntary rebirths Samsara), "extinguished", "quieted", "calmed";^[79] it is also known as "Awakening" or "Enlightenment" in the West. Buddhists believe that anybody who has achieved nirvana is in fact a Buddha.

Bodhi (Pāli and Sanskrit, in devanagari: बॊधि) is a term applied to the experience of Awakening of arahants. Bodhi literally means "awakening", but is more commonly referred to as "enlightenment". In Early Buddhism, bodhi carried a meaning synonymous to nirvana, using only some different metaphors to describe the experience, which implies the extinction of raga (greed, craving),^[80] dosa (hate, aversion)^[81] and moha (delusion).^[82] In the later school of Mahayana Buddhism, the status of nirvana was downgraded in some scriptures, coming to refer only to the extinction of greed and hate, implying that delusion was still present in one who attained nirvana, and that one needed to attain bodhi to eradicate delusion:

An important development in the Mahayana [was] that it came to separate nirvana from bodhi ('awakening' to the truth, Enlightenment), and to put a lower value on the former (Gombrich, 1992d). Originally nirvana and bodhi refer to the same thing; they merely use different metaphors for the experience. But the Mahayana tradition separated them and considered that nirvana referred only to the extinction of craving (passion and hatred), with the resultant escape from the cycle of rebirth. This interpretation ignores the third fire, delusion: the extinction of delusion is of course in the early texts identical with what can be positively expressed as gnosis, Enlightenment.

—Richard F. Gombrich, How Buddhism Began^[83]

Therefore, according to Mahayana Buddhism, the arahant has attained only nirvana, thus still being subject to delusion, while the bodhisattva not only achieves nirvana but full liberation from delusion as well. He thus attains bodhi and becomes a buddha. In Theravada Buddhism, bodhi and nirvana carry the same meaning, that of being freed from greed, hate and delusion.

The term parinirvana is also encountered in Buddhism, and this generally refers to the complete nirvana attained by the arhat at the moment of death, when the physical body expires.

Buddhas

Theravada

In Theravada doctrine, a person may awaken from the "sleep of ignorance" by directly realizing the true nature of reality; such people are called arahants and occasionally buddhas. After numerous lifetimes of spiritual striving, they have reached the end of the cycle of rebirth, no longer reincarnating as human, animal, ghost, or other being. The commentaries to the Pali Canon classify these awakened beings into three types:

• Sammasambuddha, usually just called Buddha, who discovers the truth by himself and teaches the path to awakening to others
• Paccekabuddha, who discovers the truth by himself but lacks the skill to teach others
• Savakabuddha, who receive the truth directly or indirectly from a Sammasambuddha

Bodhi and nirvana carry the same meaning, that of being freed from craving, hate, and delusion. In attaining bodhi, the arahant has overcome these obstacles. As a further distinction, the extinction of only hatred and greed (in the sensory context) with some residue of delusion, is called anagami.

Mahayana

In the Mahayana, the Buddha tends not to be viewed as merely human, but as the earthly projection of a beginningless and endless, omnipresent being (see Dharmakaya) beyond the range and reach of thought. Moreover, in certain Mahayana sutras, the Buddha, Dharma and Sangha are viewed essentially as One: all three are seen as the eternal Buddha himself.

Celestial Buddhas are individuals who no longer exist on the material plane of existence, but who still aid in the enlightenment of all beings.

Nirvana came to refer only to the extinction of greed and hate,^{[dubious – discuss]} implying that delusion was still present in one who attained Nirvana. Bodhi became a higher attainment that eradicates delusion entirely.^[83] Thus, the Arahant attains Nirvana but not Bodhi, thus still being subject to delusion, while the Buddha attains Bodhi.^{[dubious – discuss]}

The method of self-exertion or "self-power" – without reliance on an external force or being – stands in contrast to another major form of Buddhism, Pure Land, which is characterised by utmost trust in the salvific "other-power" of Amitabha Buddha. Pure Land Buddhism is a very widespread and perhaps the most faith-orientated manifestation of Buddhism and centres upon the conviction that faith in Amitabha Buddha and the chanting of homage to his name will liberate one at death into the "happy land" (安樂) or "pure land" (淨土) of Amitabha Buddha. This Buddhic realm is variously construed as a foretaste of Nirvana, or as essentially Nirvana itself. The great vow of Amitabha Buddha to rescue all beings from samsaric suffering is viewed within Pure Land Buddhism as universally efficacious, if only one has faith in the power of that vow or chants his name.

Nearly all Chinese Buddhists accept that the chances of attaining sufficient enlightenment by one's own efforts are very slim,^{[dubious – discuss]} so that Pure Land practice is essential as an "insurance policy" even if one practises something else.^[84]

Buddha eras

Buddhists believe Gautama Buddha was the first to achieve enlightenment in this Buddha era and is therefore credited with the establishment of Buddhism. A Buddha era is the stretch of history during which people remember and practice the teachings of the earliest known Buddha. This Buddha era will end when all the knowledge, evidence and teachings of Gautama Buddha have vanished. This belief therefore maintains that many Buddha eras have started and ended throughout the course of human existence.^[85][86] The Gautama Buddha, then, is the Buddha of this era, who taught directly or indirectly to all other Buddhas in it (see types of Buddhas).

In addition, Mahayana Buddhists believe there are innumerable other Buddhas in other universes.^[87] A Theravada commentary says that Buddhas arise one at a time in this world element, and not at all in others.^[88]

The idea of the decline and gradual disappearance of the teaching has been influential in East Asian Buddhism. Pure Land Buddhism holds that it has declined to the point where few, if any, are capable of following the path, so most or all must rely on the power of the Buddha Amitabha. Zen and Nichiren traditionally hold that most are incapable of following the "complicated" paths of some other schools and present what they view as a simple practice instead.

Bodhisattvas

Mahayana Buddhism puts great emphasis and, in fact, encourages anybody to follow the path of a Bodhisattva.

Bodhisattva means either "enlightened (bodhi) existence (sattva)" or "enlightenment-being" or, given the variant Sanskrit spelling satva rather than sattva, "heroic-minded one (satva) for enlightenment (bodhi)". Another translation is "Wisdom-Being".^[89]

The various divisions of Buddhism understand the word Bodhisattva in different ways. Theravada and some Mahayana sources consider a Bodhisattva as someone on the path to Buddhahood, while other Mahayana sources speak of Bodhisattvas renouncing Buddhahood,^[90][91] but especially in Mahayana Buddhism, it mainly refers to a being that compassionately refrains from entering nirvana in order to save others. So the Bodhisattva is a person who already has a considerable degree of enlightenment and seeks to use their wisdom to help other sentient beings to become liberated themselves.

While Theravada regards it as an option, Mahayana encourages everyone to follow a Bodhisattva path and to take the Bodhisattva vows. With these vows, one makes the promise to work for the complete enlightenment of all sentient beings.

A famous saying by the 8th-century Indian Buddhist scholar-saint Shantideva, which the 14th Dalai Lama often cites as his favourite verse, summarizes the Bodhisattva's intention (Bodhicitta) as follows: "For as long as space endures, and for as long as living beings remain, until then may I too abide to dispel the misery of the world."

According to the Mahayana, a Bodhisattva practices in the six perfections: giving, morality, patience, joyous effort, concentration and wisdom.
