Matsya Purana — Tārakāsura’s Austerity and Boon; Mobilization for War; Bṛhaspati’s Fourfold P...
*ब्रह्मोवाच पुत्रालं तपसा ते ऽस्तु नास्त्यसाध्यं तवाधुना वरं वृणीष्व रुचिरं यत्ते मनसि वर्तते //
*brahmovāca putrālaṃ tapasā te 'stu nāstyasādhyaṃ tavādhunā varaṃ vṛṇīṣva ruciraṃ yatte manasi vartate //
Brahmā said: “O son, your austerity is sufficient—so let it be. For you now, nothing is unattainable. Choose a splendid boon—whatever abides in your mind.”
This verse does not describe Pralaya directly; it establishes the Purāṇic principle that intense tapas can earn divine boons, which often become the narrative cause behind later cosmic events (including protection during dissolution).
It reinforces that disciplined self-control (tapas) and clarity of intention are valued virtues; for kings and householders, it implies that legitimate power and prosperity should be sought through restraint, merit, and righteous aims rather than impulse.
No specific Vāstu or temple rule is stated here; ritually, it reflects the tapas→prasāda→vara pattern that underlies many consecrations and vow-based observances in Purāṇic practice.
