"Morals", "morality", "ethics": precepts. Śīla or sīla (Pāli) in Buddhism is one of three sections of the Noble Eightfold Path, and is a code of conduct that embraces a commitment to harmony and self-restraint with the principal motivation being non-violence, or freedom from causing harm. It has been variously described as virtue, right conduct, morality, moral discipline and precept.
Sīla is an internal, aware, and intentional ethical behavior, according to one's commitment to the path of liberation. The Sanskrit and Pali word sīla is an ethical compass within self and relationships, rather than what is associated with the English word "morality" (i.e., obedience, a sense of obligation, and external constraint - all of which are quite foreign to the concept of sīla as taught by Gautama the Buddha since 588BC). In fact, the commentaries explain the word sīla by another word, samadhana, meaning "harmony" or "coordination."
Sīla is one of the three practices foundational to Buddhism and the non-sectarian Vipassana movement — sīla, samādhi, and paññā as well as the Theravadin foundations of sīla, dana, and bhavana. It is also the second pāramitā. Though some popular conceptions of these ethics carry negative connotations of severe discipline and abstinence, sīla is more than just avoiding the unwholesome.
Sīla is also wholehearted commitment to what is wholesome. Two aspects of sīla are essential to the training: right "performance" (caritta), and right "avoidance" (varitta). Honoring the precepts of sīla is considered a "great gift" (mahadana) to others, because it creates an atmosphere of trust, respect, and security. It means we pose no threat to another person's life, property, family, rights, or well-being.
