KOŚĀMBAKAVASTU SUTRA

An Explanation According to the Pāli Canon Tradition

Background

Kośāmbakavastu (The Event in the City of Kośāmbī) is an important passage in the Vinaya Piṭaka, specifically the ninth Khandhaka of the Pāli Canon. This passage records a serious historical event within the Sangha, when a dispute arose among monks in the city of Kośāmbī, in what is now Uttar Pradesh, India.

This event took place after the Buddha’s entrance into nirvana, during a period when the Sangha had to govern itself according to the rules established by the Buddha. This dispute reflects the practical challenges that the monastic community faced when applying the Vinaya to the shared life of the community.

Main Content

Kośāmbakavastu recounts how the dispute began from a small incident involving a breach of the Vinaya by monks. Instead of resolving it harmoniously and quietly, two groups of monks separated, each side insisting that it was right.

This dispute escalated into a serious schism. One group of monks at Kośāmbī openly criticized other monks, refusing to take part together in Sangha ceremonies such as Uposatha, the observance night, and Pavāraṇā, the invitation for admonition after the Vassa season. They even refused to share lodging and food with those whom they regarded as violators of the Vinaya.

When efforts at reconciliation by the elder monks failed, the situation became worse. Devotees and laypeople began to feel confused, not knowing whom they should trust. This division caused great harm to the honor and unity of the Sangha, spreading throughout the neighboring regions.

The passage records in detail the procedures that the elders attempted to carry out in order to restore harmony, the efforts to record the positions of the parties in the dispute, and finally the way unity was gradually restored through the intervention of respected monks from Magadha and other regions.
