Bhagavad Gita 9.21

ते तं भुक्त्वा स्वर्गलोकं विशालंक्षीणे पुण्ये मर्त्यलोकं विशन्ति।एव त्रयीधर्ममनुप्रपन्नागतागतं कामकामा लभन्ते॥

te taṃ bhuktvā svargalokaṃ viśālaṃkṣīṇe puṇye martyalokaṃ viśanti |eva trayīdharmamanuprapannāgatāgataṃ kāmakāmā labhante ||

They, having enjoyed the vast heaven, enter the world of mortals when their merit is exhausted; thus abiding by the injunctions of the three (Vedas) and desiring objects of desires, they attain to the state of coming and going.

Yet, although they enjoy the spacious glories of Paradise, when their merit is exhausted, they are born again into this world of mortals. They have followed the letter of the scriptures, yet, because they have sought to fulfill their own desires, they must depart and return again and again.

Our plain-language meaning of this verse is waiting for scholar review.
