A Corpus That Calls Itself Vedic

The Vaikhanasa corpus takes its name from the sage Vikhanas, and unlike the Pancharatra samhitas it does not claim status as an independent revelation standing beside the Veda; it presents itself instead as a direct ritual extension of the Taittiriya branch of the Krishna Yajurveda, continuing the domestic and public sacrificial system already laid out in that Vedic school's own grhya and dharma literature. Its foundational ritual text, the Vaikhanasa Grhyasutra, sits within that Vedic corpus proper, and the four kalpasutra manuals that build temple worship procedure on top of it are attributed to four sage disciples of Vikhanas, Bhrigu, Marichi, Kashyapa and Atri, each supplying a portion of the developed system rather than a rival account of it. This claimed continuity is also a claim about age: the Vaikhanasa community appears already in the Mahabharata and the Ramayana, and its distinctive Atma Sukta hymn shows a mix of late Vedic and early classical features that philologists read as placing the corpus earlier than the devotional Puranas, and earlier than the more clearly tantric influenced Pancharatra samhitas, though exact dating for a ritual tradition transmitted and expanded across centuries resists a single fixed date. Historians of the two systems place their divergence from a shared earlier Vaishnava ritual culture at around the third century BCE, after which each developed its own manuals, its own priestly lineage and its own claim to represent correct temple procedure.
