Matsya Purana — The Birth of Tāraka: Varāṅgī’s Lament
*ब्रह्मोवाच किमर्थं पुत्रं भूयस्त्वं नियमं क्रूरमिच्छसि आहाराभिमुखो दैत्य तन्नो ब्रूहि महाव्रत //
*brahmovāca kimarthaṃ putraṃ bhūyastvaṃ niyamaṃ krūramicchasi āhārābhimukho daitya tanno brūhi mahāvrata //
Brahmā said: “For what purpose, my son, do you again desire a harsh observance? O Daitya, though you are inclined toward food, tell us—O great-vowed one—what is your intention?”
Nothing directly about Pralaya is stated here; the verse focuses on Brahmā scrutinizing the motive behind a severe vow (niyama), a common Purāṇic theme preceding boons and cosmic consequences.
It underscores a dharmic principle applicable to kings and householders: discipline and vows should be guided by clear, ethical purpose—Brahmā’s questioning models accountability for one’s intentions before undertaking extreme practices.
The ritual point is the emphasis on niyama/vrata (formal observance). No Vāstu or temple-building rule appears in this specific verse, but it reflects the Purāṇic insistence that rites and austerities be undertaken with declared intent and proper restraint.
