Matsya Purana — Manifestation of Kauśikī
ततस्तत्याज भृङ्गाङ्गं फुल्लनीलोत्पलत्वचम् //
tatastatyāja bhṛṅgāṅgaṃ phullanīlotpalatvacam //
Then he cast off that bee-like body, whose skin bore the hue of a fully blossomed blue lotus.
This verse does not directly discuss Pralaya; it focuses on a transformation motif—casting off a prior form—common in Puranic narration rather than cosmic dissolution.
It is not a prescriptive dharma-verse; indirectly, it reinforces the Purāṇic theme of impermanence of external forms, which supports vairāgya (detachment) often advised to kings and householders in broader Matsya Purana ethics.
No explicit Vāstu or ritual procedure is stated; the lotus-color imagery is, however, a common iconographic aesthetic used across temple art and pratima descriptions.
