janma te mayy asau papo
ma vidyan madhusudana
kamsad aham adhira-dhih
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O Madhusudana, because of Your appearance, I am becoming more and more anxious in fear of Kamsa. Therefore, please arrange for that sinful Kamsa to be unable to understand that You have taken birth from my womb.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Devaki addressed the Supreme Personality of Godhead as Madhusudana. She was aware that the Lord had killed many demons like Madhu who were hundreds and thousands of times more powerful than Kamsa, yet because of affection for the transcendental child, she believed that Kamsa could kill Him. Instead of thinking of the unlimited power of the Lord, she thought of the Lord with affection, and therefore she requested the transcendental child to disappear.
