Matsya Purana — The Birth of Tāraka: Varāṅgī’s Lament
*ब्रह्मोवाच अलं ते तपसा वत्स मा क्लेशे दुस्तरे विश पुत्रस्ते तारको नाम भविष्यति महाबलः //
*brahmovāca alaṃ te tapasā vatsa mā kleśe dustare viśa putraste tārako nāma bhaviṣyati mahābalaḥ //
Brahmā said: “Enough, dear child, with this austerity—do not torment yourself with a hardship so difficult to endure. A son of yours will be born, named Tāraka, and he will be exceedingly mighty.”
This verse does not discuss Pralaya; it focuses on tapas (austerity) leading to a divine assurance of progeny—an episode within mythic genealogy rather than cosmic dissolution.
Indirectly, it presents a Dharmic theme: intense discipline (tapas) can yield results, but needless self-torment is discouraged—suggesting balance and purpose in vows and duties rather than destructive extremes.
No Vāstu/temple-building rule is stated here; the ritual implication is the broader idea that austerities and vows (tapas) are potent, yet should be undertaken with discernment and within bearable limits.
