Matsya Purana — Paurava Genealogy
ब्रह्माणं कल्पयामास स वै वाजसनेयकम् स वैशम्पायनेनैव शप्तः किल महर्षिणा //
brahmāṇaṃ kalpayāmāsa sa vai vājasaneyakam sa vaiśampāyanenaiva śaptaḥ kila maharṣiṇā //
He is said to have composed (or arranged) a sacred Brahmanical teaching in the Vājasaneyī tradition; and indeed, it is told, he was cursed by the great sage Vaiśampāyana.
This verse does not address Pralaya; it focuses on Vedic tradition (the Vājasaneyi line) and a rishi-related curse narrative.
Indirectly, it underscores the Purāṇic ethic of reverence toward sages and disciplined transmission of sacred learning—values expected of rulers and householders alike.
No Vāstu or temple-architecture rule is stated here; the ritual relevance is the mention of the Vājasaneyi (White Yajurveda) tradition, implying authoritative Vedic recensional transmission.
