Fully ordained Buddhist nuns – people & concepts

A bhikkhunī or bhikṣuṇī is a fully ordained female monastic in Buddhism. Male monastics are called bhikkhus. Both bhikkhunis and bhikkhus live by the Vinaya, a set of rules. Until recently, the lineages of female monastics only remained in Mahayana Buddhism and thus are prevalent in countries such as China, Korea, Taiwan and Vietnam but a few women have taken the full monastic vows in the Theravada and Vajrayana schools over the last decade. .
