Matsya Purana — The Birth of Tāraka: Varāṅgī’s Lament
यावदब्दसहस्रेण निराहारस्य यत्फलम् क्षणेनैकेन तल्लभ्यं त्यक्त्वाहारमुपस्थितम् //
yāvadabdasahasreṇa nirāhārasya yatphalam kṣaṇenaikena tallabhyaṃ tyaktvāhāramupasthitam //
Whatever merit is gained by remaining without food for a thousand years—one obtains that very fruit in a single moment, by renouncing the food that is present and ready at hand.
This verse does not describe Pralaya; it teaches a dharmic principle about tapas: immediate renunciation of an available pleasure can equal the merit of prolonged austerity.
It frames self-restraint as a high-value dharma: a king or householder gains great merit by refusing indulgence even when legitimately available, strengthening discipline, ethical governance, and mastery over the senses.
No Vastu or temple-architecture rule is stated; the ritual takeaway is vrata-ethics—true austerity is measured by renouncing what is immediately accessible, not merely by duration.
