Matsya Purana — Tārakāsura’s Austerity and Boon; Mobilization for War; Bṛhaspati’s Fourfold P...
*तारक उवाच शृणुध्वमसुराः सर्वे वाक्यं मम महाबलाः श्रेयसे क्रियतां बुद्धिः सर्वैः कृत्यस्य संविधौ //
*tāraka uvāca śṛṇudhvamasurāḥ sarve vākyaṃ mama mahābalāḥ śreyase kriyatāṃ buddhiḥ sarvaiḥ kṛtyasya saṃvidhau //
Tāraka said: “Hear my words, all you Asuras of great might. Let each of you apply your intelligence to what is truly beneficial, as we deliberate together on the proper course of action.”
This verse does not address pralaya; it introduces a counsel scene where Tāraka urges collective deliberation for a beneficial plan.
It reflects the ethical-practical ideal of seeking śreyas (true welfare) through consultation and sound judgment before acting—akin to a king’s need for mantrana (counsel) and a householder’s need for careful decision-making.
No direct Vāstu or ritual rule appears here; the key takeaway is procedural—proper ‘saṃvidhi’ (orderly planning) before undertaking any undertaking.
