Vinaya

n. (Buddhism) school of Buddhism that stresses devotion to ethical principles and disciplined conduct particularly to the monastic rules

The Vinaya (a word in Pāli as well as in Sanskrit, with literal meaning 'leading out', 'education', 'discipline') is the regulatory framework for the Buddhist monastic community, or sangha, based in the canonical texts called Vinaya Pitaka. The teachings of the Buddha, or Buddhadharma can be divided into two broad categories: 'Dharma' or doctrine, and 'Vinaya', or discipline. Another term for Buddhism is dharmavinaya.
