दत्त्वा स्वजरसं तस्मादाददे विगतस्पृह: ॥ २१ ॥
tadīyaṁ pūrave vayaḥ
dattvā sva-jarasaṁ tasmād
iti uktvā — saying this; nāhuṣaḥ — Mahārāja Yayāti, the son of King Nahuṣa; jāyām — unto his wife, Devayānī; tadīyam — his own; pūrave — unto his son Pūru; vayaḥ — youth; dattvā — delivering; sva-jarasam — his own invalidity and old age; tasmāt — from him; ādade — took back; vigata-spṛhaḥ — being freed from all material lusty desires.
Śukadeva Gosvāmī said: After speaking in this way to his wife, Devayānī, King Yayāti, who was now free from all material desires, called his youngest son, Pūru, and returned Pūru’s youth in exchange for his own old age.
