Dr. Chatsumarn Kabilsingh has translated the monastic rules of Buddhist nuns or the Patimokkha of the Six Schools, which will help us to learn and compare Theravada, Mahasanghika, Mahisasaka, Sarvastivada, Dhamagupta and Mula-Sarvastivada. The study of the patimokkha also provides insight into the historical context from which the rules took place. This translation will also provide valuable material for concerned Buddhist scholars.
