Matsya Purana — Uma’s Austerities and the Slaying of the Deceiver Asura ĀḌi
विचिन्त्यासीद्वरं दत्तं स पुरा पद्मजन्मना हते तदान्धके दैत्ये गिरिशेनामरद्विषि //
vicintyāsīdvaraṃ dattaṃ sa purā padmajanmanā hate tadāndhake daitye giriśenāmaradviṣi //
Reflecting, he recalled the boon once granted by Padmajanman (Brahmā), when Andhaka—the demon who hated the gods—was slain by Girīśa (Śiva).
This verse does not describe Pralaya; it highlights Puranic causality through boons (vara) and their karmic/ethical consequences within a Deva–Asura conflict narrative.
Indirectly, it teaches that power obtained through boons or privilege must be governed by dharma—since even divinely granted advantages can lead to ruin when used in hostility toward the righteous (the ‘amaras’).
No Vāstu or temple-architecture rule is stated here; the verse is purely narrative, referencing Brahmā’s boon and Śiva’s slaying of Andhaka.
