Kaṁsa is both a great diplomat and a very sinful man. Therefore, having heard from Yoga-māyā, the daughter of Devakī, that the child who will kill him has already been born somewhere else, having heard that the eighth pregnancy of Devakī could not bring forth a female child, and having understood your friendship with Vasudeva, Kaṁsa, upon hearing that the purificatory process has been performed by me, the priest of the Yadu dynasty, may certainly consider all these points and suspect that Kṛṣṇa is the son of Devakī and Vasudeva. Then he might take steps to kill Kṛṣṇa. That would be a catastrophe.
