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.
