Gita Chapter 9.21 to 9.25

Te tam bhuktwaa swargalokam vishaalam
Ksheene punye martyalokam vishanti;
Evam trayeedharmamanuprapannaa
Gataagatam kaamakaamaa labhante.
21. They, having enjoyed the vast heaven, enter the world of mortals when their merits are exhausted; thus abiding by the injunctions of the three (Vedas) and desiring (objects of) desires, they attain to the state of going and returning.
COMMENTARY: When their accumulated merits are exhausted, they come to this world again. They have no independence.

Ananyaashchintayanto maam ye janaah paryupaasate;
Teshaam nityaabhiyuktaanaam yogakshemam vahaamyaham.
22. To those men who worship Me alone, thinking of no other, of those ever united, I secure what is not already possessed and preserve what they already possess.

Ye’pyanyadevataa bhaktaa yajante shraddhayaa’nvitaah;
Te’pi maameva kaunteya yajantyavidhipoorvakam.
23. Even those devotees who, endowed with faith, worship other gods, worship Me only, O Arjuna, but by the wrong method!

Aham hi sarvayajnaanaam bhoktaa cha prabhureva cha;
Na tu maamabhijaananti tattwenaatashchyavanti te.
24. (For) I alone am the enjoyer and also the Lord of all sacrifices; but they do not know Me in essence (in reality), and hence they fall (return to this mortal world).

Yaanti devavrataa devaan pitreen yaanti pitrivrataah;
Bhutaani yaanti bhutejyaa yaanti madyaajino’pi maam.
25. The worshippers of the gods go to them; to the manes go the ancestor-worshippers; to the Deities who preside over the elements go their worshippers; My devotees come to Me.
