 The two most important systems of moral discipline in Buddhism are the Five Precepts, which apply to lay people, and the Vows of Individual Liberation (Skt. prātimokṣa) which apply to monks and nuns. Accepting these commitments is a crucial part of what defines someone as a Buddhist lay person or as a Buddhist monastic. The Five Precepts are quite similar to basic lists of prohibitions in other great world religions: those who take them make a commitment to refrain from killing, stealing, sexual misconduct, lying, and drunkenness. The Vows of Individual Liberation are stricter, ruling out all forms of sexual activity and laying down detailed regulations for monastic etiquette and deportment.
