Here is an example of the extreme mercy of the Lord, even to His enemy. It is said that a noble man accepts the good qualities of a person of doubtful character, just as one accepts nectar from a stock of poison. In His babyhood, He was administered deadly poison by Putana, a she-demon who tried to kill the wonderful baby. And because she was a demon, it was impossible for her to know that the Supreme Lord, even though playing the part of a baby, was no one less than the same Supreme Personality of Godhead. His value as the Supreme Lord did not diminish upon His becoming a baby to please His devotee Yasoda. The Lord may assume the form of a baby or a shape other than that of a human being, but it doesnt make the slightest difference; He is always the same Supreme. A living creature, however powerful he may become by dint of severe penance, can never become equal to the Supreme Lord.
