Matsya Purana — Prologue to the Matsya Purana and the Manu–Pralaya Rescue Narrative
भैरवत्वं भवस्यापि पुरारित्वं च केन हि कस्य हेतोः कपालित्वं जगाम वृषभध्वजः //
bhairavatvaṃ bhavasyāpi purāritvaṃ ca kena hi kasya hetoḥ kapālitvaṃ jagāma vṛṣabhadhvajaḥ //
By whom, indeed, did Bhava (Śiva) come to be known as Bhairava, and as the Slayer of Tripura? And for what reason did the Bull-bannered Lord (Śiva) assume the state of being a skull-bearer (Kapālin)?
This verse does not describe Pralaya directly; it functions as an opening theological inquiry, asking for the origins (etiology) of Śiva’s fierce and ascetic epithets—Bhairava, Purāri, and Kapālin.
Indirectly, it models the kingly duty of seeking authoritative sacred knowledge: Manu’s questioning frames dharmic governance as grounded in understanding divine precedents, vows, and the moral causes behind renowned acts and titles.
Architectural rules are not stated here, but the verse is ritually significant: it points to Śaiva forms (Bhairava) and vows (Kapālin), themes that commonly inform temple iconography, deity selection, and the rationale for specific worship modes in Purāṇic practice.
