Toh 5Detailed Explanations on Nuns’ Discipline

Sūtra of Detailed Explanations on the Discipline of Nuns (Bhikṣuṇīvinayavibhaṅga)

Context

The Sūtra of Detailed Explanations on the Discipline of Nuns (Bhikṣuṇīvinayavibhaṅga) is an important text in the Northern Transmission canon of Buddhism, contained in the Kangyur — the standard collection of scriptures of Tibetan Buddhism. This work focuses on the Vinaya, or rules of discipline, specifically for nuns, extending from basic regulations to detailed explanations and applications in practice.

In the Tibetan Mahāyāna tradition, Vinaya is not only a code of conduct but also an expression of compassion and voluntary discipline. The establishment of a separate discipline for nuns reflects Buddha Śākyamuni’s recognition of women in spiritual practice. According to tradition, the first nun was Mahāprajāpatī Gautamī — the Buddha’s foster mother — and from that time onward, communities of female renunciants developed strongly throughout Buddhist civilizations.

Main Content

The Bhikṣuṇīvinayavibhaṅga is a part of the Mūlasarvāstivāda Vinaya, the legal tradition chosen for Tibetan Buddhism. This scripture provides in-depth explanations of each rule, from basic regulations concerning body, speech, and mind to complex situations in communal life.

The main content includes prohibitions (Prajñapti), wrongful actions (aparādhā), and ways of remedying them through repentance and re-ordination. The scripture does not merely list rules, but also explains the psychological and ethical roots of each rule. For example, rules concerning sexuality are not mechanisms of punishment, but guidance for protecting purity of mind and preserving the honor of the community of nuns.

The scripture also discusses the complex relationships between nuns and monks, regulations concerning communal living, rites of Dharma joy, and methods for handling violations according to their degree of gravity.
