Verse
ते तं भुक्त्वा स्वर्गलोकं विशालंक्षीणे पुण्ये मर्त्यलोकं विशन्ति ।एवं त्रयीधर्ममनुप्रपन्नागतागतं कामकामा लभन्ते ॥
They, having enjoyed heavenly worlds of larger felicities, the reward of their good deeds exhausted, return to mortal existence. Resorting to the virtues enjoined by the three Vedas, seeking the satisfaction of desire, they follow the cycle of birth and death.
Gītā 9·21
