यद्धेतो: पुत्रमरणं यद्धेतोर्बन्धनं तयो: ॥ ६ ॥
pitror vṛjinam āryayoḥ
yad-dhetor bandhanaṁ tayoḥ
Just see how much suffering I have caused My offenseless parents! Because of Me their sons were killed and they themselves imprisoned.
Because Kaṁsa had heard a prophecy that the eighth son of Devakī would kill him, he tried to kill all her children. For the same reason, he imprisoned her and her husband, Vasudeva.
