Āpatti and Anāpatti: Understanding Sectarian Division in the Early Buddhist Saṅgha

Abstract

This paper examines the role of anāpatti, the Vinaya concept of ‘no offence,’ denoting conditions under which an otherwise transgressive act is exempt from penalty in the formation of the early Buddhist schisms. While scholarly accounts of sectarian division in early Buddhism have foregrounded doctrinal disputes and regional diversification, the specific role of exceptions to monastic norms has received little sustained attention. Drawing on the Pāli Vinaya Piṭaka. This paper argues that the ten-point controversy (dasavatthu) of the Second Buddhist Council at Vaiśālī, along with the five-point (pañcavatthu) disputes attributed to Mahādeva, are best understood not simply as violations of precepts but as contested claims about the legitimate scope of anāpatti . The paper traces the historical development of the Saṅgha from the post-parinibbāna period through Aśoka’s missionary expansion, establishing the political and geographical conditions under which divergent interpretations of exception arose. It then re-reads the major schism events through the lens of anāpatti, drawing on the Devadatta episode and the Bimbisāra ordination adjustment as illustrations of how the Buddha himself operationalised the concept of legitimate exception. The analysis suggests that schism was not merely doctrinal disagreement but a consequence of irreconcilable interpretations of when the rules could be set aside.
