Matsya Purana — Yayāti and His Sons: The Exchange of Youth and Old Age
तुर्वसो प्रतिपद्यस्व पाप्मानं जरया सह यौवनेन चरेयं वै विषयांस्तव पुत्रक //
turvaso pratipadyasva pāpmānaṃ jarayā saha yauvanena careyaṃ vai viṣayāṃstava putraka //
O Turvasu, accept this burden of sin along with old age; and with your youth, my son, I shall indeed enjoy the objects of sense.
This verse does not discuss Pralaya; it focuses on a moral-royal episode where Yayati seeks to transfer the effects of old age and the taint of sin to obtain youth for worldly enjoyment.
It highlights the ethical tension between royal/householder enjoyment (kāma) and responsibility (dharma): a ruler’s craving for sense-pleasures can lead to morally fraught choices, making the episode a cautionary teaching about self-control and the consequences of desire.
No Vastu, temple-construction, or ritual procedure is mentioned in this verse; it is part of the Yayati narrative concerning youth, old age, and the fruits of actions.
