Khandhaka

The Khandhaka moves beyond the Suttavibhanga's individual rules of personal conduct into the organizational machinery required to run a growing monastic institution, covering, across its Mahavagga and Cullavagga sections, the procedures for ordaining new monks and nuns, the conduct of the fortnightly uposatha observance at which the Patimokkha rules are recited communally, the annual three month rains retreat during which wandering ascetics settle in one place, and detailed regulations on robes, dwellings, food, medicine and the resolution of disputes within the community. Its opening chapters of the Mahavagga narrate, in continuous story form rather than as bare regulation, the period immediately following the Buddha's enlightenment, his first sermon, the ordination of his earliest disciples, and the gradual growth of the sangha, giving this division a narrative, biographical quality closer to the suttas than to the more technical Suttavibhanga.

The Cullavagga closes the division with an account of the two earliest and most consequential councils in Buddhist history, the First Council convened shortly after the Buddha's death to formally recite and fix the teaching and the monastic rules, and the Second Council roughly a century later, convened specifically to resolve a dispute over ten points of monastic practice that some monks considered legitimate relaxations and others considered clear violations.

The Khandhaka's account of the Second Buddhist Council is treated by historians as some of the most reliable historical material anywhere in the early Buddhist canon, since its ten disputed points, including whether monks could accept gold and silver donations and certain details of how the uposatha ceremony could be conducted, describe a concrete, plausible institutional disagreement rather than legendary or doctrinal material, and most scholars accept that some form of this council genuinely occurred roughly a century after the Buddha's death, making it one of the few episodes in the earliest layer of Buddhist textual history with reasonably firm historical anchoring. That council's resolution, and the underlying tensions it only partially settled, is widely regarded by scholars as an early precursor to the broader splits into separate ordination lineages and doctrinal schools that would eventually produce, centuries later, the divide between Theravada and the various Mahayana traditions, even though the immediate Second Council dispute itself concerned monastic discipline rather than the philosophical questions that later separated the traditions more decisively.

The Khandhaka's ordination procedures, refined and elaborated across these two sections, remain in active liturgical use in Theravada monasteries today essentially unchanged in their core structure, making this one of the oldest continuously performed formal religious ceremonies still practiced according to its original canonical script.
