San Mu Kd 10Karmavastu

Exposition of the Karmavastu Sūtra

Background

Karmavastu (Pāli: Kammavastu), or "The Chapter on Formal Acts," is an important part of the Vinaya Piṭaka of the Theravāda Buddhist tradition. This work belongs to the Vinaya collection of Phạm Lâm, the Saṃyutta Nikāya, or various Vinaya collections depending on the Theravāda school. Karmavastu is not an independent sūtra, but a careful section on decisions, rules, and procedures related to the communal activity of the Sangha (Saṃgha).

The compositional context of Karmavastu is connected with the development of the Sangha after the Buddha’s nirvana. As the monastic community increased in number and diversity, clear regulations were needed to maintain discipline, fairness, and unity in common activities. The arhat elders compiled these rules based on the Buddha’s teachings, in order to protect and develop the Dharma.

Main Content

Karmavastu focuses on matters related to "Karma" (Pāli: Kamma) in the broad sense, not the karmic causality of rebirth, but the formal acts, decisions, and official procedures of the Sangha. This section gives detailed regulations concerning:

First, the forms of Karma officially recognized, such as Upasampada (new bhikkhu ordination), Pavāraṇā (invitation to declare faults), and collective decisions (Saṅgha-kamma). Each of these acts must follow strict ritual procedure in order to have legal validity within the Sangha.

Second, Karmavastu regulates the conditions for a Karma to be valid: there must be an assembly (Parisā) properly informed, the motion (Ñatti), or first announcement, must be clear, and the decision (Anusavana) must be approved by the entire monastic community. If any element is lacking, that Karma is considered invalid (Adinnalabha).

Third, this section also explains exceptions and complex situations: when there is dispute, when bhikṣus are divided, or when it is not possible to gather the entire community. These regulations reflect the practical wisdom of the Buddha.
