CC Madhya 22.140
deva-ṛṣi-pitrādikera kabhu nahe ṛṇī
“If a person gives up all material desires and completely engages in the transcendental loving service of Kṛṣṇa, as enjoined in the revealed scriptures, he is never indebted to the demigods, sages or forefathers.
After birth, every man is indebted in so many ways. He is indebted to the demigods for their supplying necessities like air, light and water. When one takes advantage of the Vedic literatures, one becomes indebted to great sages like Vyāsadeva, Nārada, Devala and Asita. When one takes birth in a particular family, he becomes indebted to his forefathers. We are even indebted to common living entities like cows, from whom we take milk. Because we accept service from so many animals, we become indebted. However, if one is completely engaged in the Lord’s devotional service, he is absolved of all debts. This is confirmed in the following verse, quoted from Śrīmad-Bhāgavatam (11.5.41).
