Matsya Purana — Yayāti and His Sons: The Exchange of Youth and Old Age
त्वं यदो प्रतिपद्यस्व पाप्मानं जरया सह यौवनेन त्वदीयेन चरेयं विषयानहम् //
tvaṃ yado pratipadyasva pāpmānaṃ jarayā saha yauvanena tvadīyena careyaṃ viṣayānaham //
O Yadu, when you take upon yourself sin together with old age, then with your youth—now belonging to me—may I enjoy the objects of the senses.
This verse does not discuss pralaya or cosmology; it is an ethical-narrative statement about transferring the burden of sin and old age in exchange for youth and sense-enjoyment.
It highlights a dharmic warning: pursuing pleasures while attempting to shift consequences (sin/decay) onto another is morally suspect, reinforcing personal responsibility and restraint expected of householders and rulers.
No Vastu, temple iconography, or ritual procedure is stated in this verse; its focus is psychological and ethical—desire, aging, and accountability.
