Five Nights and a Growing Canon

The name Pancharatra literally means five nights, and tradition traces it to a myth in which Narayana taught a sacrifice lasting five nights to a group of sages, a foundational story the samhitas themselves repeat in various forms to establish their own divine authority. In practice the corpus is a rolling accumulation rather than a text closed at a single moment: composition and revision ran from roughly the sixth century CE into the medieval period, producing well over one hundred named samhitas of uneven length, completeness and survival, several known only through citation in later digests rather than as intact manuscripts. Among the works most consistently cited by later theologians are the Ahirbudhnya Samhita, prized for its systematic cosmology; the Jayakhya Samhita and Sattvata Samhita, both central to ritual practice; the Paushkara Samhita; and the Parama Samhita.

Unlike the Vedic corpus, which Hindu orthodoxy treats as a closed and eternally fixed body of revelation, the Pancharatra samhitas present themselves individually as direct speech from Vishnu or his emanations, an authorship claim that let the tradition keep producing new authoritative texts long after the Vedic canon itself had closed. That same claim to independent revelation, standing alongside rather than growing out of the Veda, is precisely what made the corpus doctrinally controversial to more conservative Vedic ritualists for centuries, even as it steadily gained temple authority across the Vaishnava south.
