The five precepts (; ) or five rules of training (; ) is the most important system of morality for Buddhist lay people. They constitute the basic code of ethics to be respected by lay followers of Buddhism. The precepts are commitments to abstain from killing living beings, stealing, sexual misconduct, lying and intoxication. Within the Buddhist doctrine, they are meant to develop mind and character to make progress on the path to enlightenment. They are sometimes referred to as the Śrāvakayāna precepts in the Mahāyāna tradition, contrasting them with the bodhisattva precepts. The five precepts form the basis of several parts of Buddhist doctrine, both lay and monastic. With regard to their fundamental role in Buddhist ethics, they have been compared with the Ten Commandments in Abrahamic religions or the ethical codes of Confucianism. The precepts have been connected with utilitarianist, deontological and virtue approaches to ethics, though by 2017, such categorization by western terminology had mostly been abandoned by scholars. The precepts have been compared with human rights because of their universal nature, and some scholars argue they can complement the concept of human rights.

The five precepts were common to the religious milieu of 6th-century BCE India, but the Buddha's focus on awareness through the fifth precept was unique. As shown in Early Buddhist Texts, the precepts grew to be more important, and finally became a condition for membership of the Buddhist religion. When Buddhism spread to different places and people, the role of the precepts began to vary. In countries where Buddhism had to compete with other religions, such as China, the ritual of undertaking the five precepts developed into an initiation ceremony to become a Buddhist layperson. On the other hand, in countries with little competition from other religions, such as Thailand, the ceremony has had little relation to the rite of becoming Buddhist, as many people are presumed Buddhist from birth.

Undertaking and upholding the five precepts is based on the principle of non-harming (Pāli and ). The Pali Canon recommends one to compare oneself with others, and on the basis of that, not to hurt others. Compassion and a belief in karmic retribution form the foundation of the precepts. Undertaking the five precepts is part of regular lay devotional practice, both at home and at the local temple. However, the extent to which people keep them differs per region and time. People keep them with an intention to develop themselves, but also out of fear of a bad rebirth.

The first precept consists of a prohibition of killing, both humans and all animals. Scholars have interpreted Buddhist texts about the precepts as an opposition to and prohibition of capital punishment, suicide, abortion and euthanasia. In practice, however, many Buddhist countries still use the death penalty and abortion is legal in some Buddhist countries. With regard to abortion, Buddhist countries take the middle ground, by condemning though not prohibiting it fully. The Buddhist attitude to violence is generally interpreted as opposing all warfare, but some scholars have raised exceptions found in later texts. The second precept prohibits theft and related activities such as fraud and forgery. The third precept refers to sexual misconduct, and has been defined by modern teachers with terms such as sexual responsibility and long-term commitment. The fourth precept involves falsehood spoken or committed to by action, as well as malicious speech, harsh speech and gossip. The fifth precept prohibits intoxication through alcohol, drugs, or other means. Early Buddhist Texts nearly always condemn alcohol, and so do Chinese Buddhist post-canonical texts. Smoking is sometimes also included here.

In modern times, traditional Buddhist countries have seen revival movements to promote the five precepts. As for the West, the precepts play a major role in Buddhist organizations. They have also been integrated into mindfulness training programs, though many mindfulness specialists do not support this because of the precepts' religious import. Lastly, many conflict prevention programs make use of the precepts.

Role in Buddhist doctrine

Buddhist scriptures explain the five precepts as the minimal standard of Buddhist morality. It is the most important system of morality in Buddhism, together with the monastic rules. Śīla (Sanskrit; ) is used to refer to Buddhist precepts, including the five. But the word also refers to the virtue and morality which lies at the foundation of the spiritual path to enlightenment, which is the first of the three forms of training on the path. Thus, the precepts are rules or guidelines to develop mind and character to make progress on the path to enlightenment. The five precepts are part of the right speech, action and livelihood aspects of the Noble Eightfold Path, the core teaching of Buddhism. Moreover, the practice of the five precepts and other parts of śīla are described as forms of merit-making, means to create good karma. The five precepts have been described as social values that bring harmony to society, and breaches of the precepts described as antithetical to a harmonious society. On a similar note, in Buddhist texts, the ideal, righteous society is one in which people keep the five precepts.

Comparing different parts of Buddhist doctrine, the five precepts form the basis of the eight precepts, which are lay precepts stricter than the five precepts, similar to monastic precepts. Secondly, the five precepts form the first half of the ten or eleven precepts for a person aiming to become a Buddha (bodhisattva), as mentioned in the Brahmajala Sūtra of the Mahāyāna tradition. Contrasting these precepts with the five precepts, the latter were commonly referred to by Mahāyānists as the śrāvakayāna precepts, or the precepts of those aiming to become enlightened disciples (; ) of a Buddha, but not Buddhas themselves. The ten–eleven bodhisattva precepts presuppose the five precepts, and are partly based on them. The five precepts are also partly found in the teaching called the ten good courses of action, referred to in Theravāda () and Tibetan Buddhism (; ). Finally, the first four of the five precepts are very similar to the most fundamental rules of monastic discipline (), and may have influenced their development.

In conclusion, the five precepts lie at the foundation of all Buddhist practice, and in that respect, can be compared with the Ten Commandments in Christianity and Judaism or the ethical codes of Confucianism.

History The five precepts were part of Early Buddhism and are common to nearly all schools of Buddhism. In Early Buddhism, the five precepts were regarded as an ethic of restraint, to restrain unwholesome tendencies and thereby purify one's being to attain enlightenment. The five precepts were based on the pañcaśīla, prohibitions for pre-Buddhist Brahmanic priests, which were adopted in many Indic religions around 6th century BCE. The first four Buddhist precepts were nearly identical to these pañcaśīla, but the fifth precept, the prohibition on intoxication, was new in Buddhism: the Buddha's emphasis on awareness () was unique.

In some schools of ancient Indic Buddhism, Buddhist devotees could choose to adhere to only a number of precepts, instead of the complete five. The schools that would survive in later periods, however, that is Theravāda and Mahāyāna Buddhism, were both ambiguous about this practice. Some early Mahāyāna texts allow it, but some do not; Theravāda texts do not discuss such selective practice at all.

The prohibition on killing had motivated early Buddhists to form a stance against animal sacrifice, a common religious ritual practice in ancient India. According to the Pāli Canon, however, early Buddhists did not adopt a vegetarian lifestyle.

In Early Buddhist Texts, the role of the five precepts gradually develops. First of all, the precepts are combined with a declaration of faith in the Triple Gem (the Buddha, his teaching and the monastic community). Next, the precepts develop to become the foundation of lay practice. The precepts are seen as a preliminary condition for the higher development of the mind. At a third stage in the texts, the precepts are actually mentioned together with the triple gem, as though they are part of it. Lastly, the precepts, together with the triple gem, become a required condition for the practice of Buddhism, as laypeople have to undergo a formal initiation to become a member of the Buddhist religion. When Buddhism spread to different places and people, the role of the precepts began to vary. In countries in which Buddhism was adopted as the main religion without much competition from other religious disciplines, such as Thailand, the relation between the initiation of a layperson and the five precepts has been virtually non-existent. In such countries, the taking of the precepts has become a sort of ritual cleansing ceremony. People are presumed Buddhist from birth without much of an initiation. The precepts are often committed to by new followers as part of their installment, yet this is not very pronounced. However, in some countries like China, where Buddhism was not the only religion, the precepts became an ordination ceremony to initiate laypeople into the Buddhist religion.

In China, the five precepts were introduced in the first centuries CE, both in their śrāvakayāna and bodhisattva formats. During this time, it was particularly Buddhist teachers who promoted abstinence from alcohol (the fifth precept), since Daoism and other thought systems emphasized moderation rather than full abstinence. Chinese Buddhists interpreted the fifth precept strictly, even more so than in Indic Buddhism. For example, the monk Daoshi ( 600–683) dedicated large sections of his encyclopedic writings to abstinence from alcohol. However, in some parts of China, such as Dunhuang, considerable evidence has been found of alcohol consumption among both lay people and monastics. Later, from the 8th century onward, strict attitudes of abstinence led to a development of a distinct tea culture among Chinese monastics and lay intellectuals, in which tea gatherings replaced gatherings with alcoholic beverages, and were advocated as such. These strict attitudes were formed partly because of the religious writings, but may also have been affected by the bloody An Lushan Rebellion of 775, which had a sobering effect on 8th-century Chinese society. When the five precepts were integrated in Chinese society, they were associated and connected with karma, Chinese cosmology and medicine, a Daoist worldview, and Confucian virtue ethics.

Ceremonies

In Pāli tradition

In the Theravāda tradition, the precepts are recited in a standardized fashion, using Pāli language. In Thailand, a leading lay person will normally request the monk to administer the precepts by reciting the following three times:

After this, the monk administering the precepts will recite a reverential line of text to introduce the ceremony, after which he guides the lay people in declaring that they take their refuge in the three refuges or triple gem.

He then continues with reciting the five precepts: "I undertake the training-precept to abstain from onslaught on breathing beings." () "I undertake the training-precept to abstain from taking what is not given." () "I undertake the training-precept to abstain from sexual misconduct." () "I undertake the training-precept to abstain from false speech." () "I undertake the training-precept to abstain from alcoholic drink or drugs that are an opportunity for heedlessness." ()

After the lay people have repeated the five precepts after the monk, the monk will close the ceremony reciting:
