SB 10.4.21

As stated in the Brahma-saṁhitā (5.54) : yas tv indra-gopam athavendram aho sva-karma- bandhānurūpa-phala-bhājanam ātanoti karmāṇi nirdahati kintu ca bhakti-bhājāṁ govindam ādi-puruṣaṁ tam ahaṁ bhajāmi Everyone, beginning from the small insect known as indra-gopa up to Indra, the King of the heavenly planets, is obliged to undergo the results of his fruitive activities. We may superficially see that one is suffering or enjoying because of some external causes, but the real cause is one’s own fruitive activities. Even when someone kills someone else, it is to be understood that the person who was killed met the fruitive results of his own work and that the man who killed him acted as the agent of material nature. Thus Kaṁsa begged Devakī’s pardon by analyzing the matter deeply. He was not the cause of the death of Devakī’s sons. Rather, this was their own destiny. Under the circumstances, Devakī should excuse Kaṁsa and forget his past deeds without lamentation. Kaṁsa admitted his own fault, but whatever he had done was under the control of providence. Kaṁsa might have been the immediate cause for the death of Devakī’s sons, but the remote cause was their past deeds. This was an actual fact.
