Matsya Purana — The Birth of Tāraka: Varāṅgī’s Lament
तपः कर्तुं पुनर्दैत्यो व्यवस्वेत महाबलः ज्ञात्वा तु तस्य संकल्पं ब्रह्मा क्रूरतरं पुनः //
tapaḥ kartuṃ punardaityo vyavasveta mahābalaḥ jñātvā tu tasya saṃkalpaṃ brahmā krūrataraṃ punaḥ //
Then the mighty Daitya again resolved to undertake austerities (tapas). But Brahmā, having understood his intention, once more devised a harsher counter-course.
It does not describe Pralaya directly; it highlights cosmic administration—how Brahmā monitors and checks disruptive power gained through tapas to preserve order in the created world.
It implies a governance ethic: power (even if acquired through discipline) must be supervised and restrained when aimed at harmful ends—mirroring a king’s duty to anticipate threats and act proportionately to protect dharma.
No Vāstu or temple-rule detail appears in this verse; the only ritual motif is tapas (austerity) as a spiritual “technology,” paired with the idea that intention (saṅkalpa) determines its moral outcome.
