When Krishna gives everything why go to anyone else?
Lord Krishna’s transcendental qualities are so
sublime that there is no need to divert one’s attention to any other
activities. His behavior with the devotees is so exalted that a devotee
need not try to divert his attention to any other worship. It is said
that the demoniac Putana came to kill Krishna by poisoning Him, but because
Krishna was pleased to suck her breast, she was given the same position as
His mother. Devotees pray, therefore, that if a demon who wanted to kill
Krishna gets such an exalted position, why should they go to anyone other
than Krishna for their worshipful attachment? There are two kinds of
religious activities: one for material advancement and the other for
spiritual advancement. By taking shelter under the lotus feet of Krishna,
one is endowed with both kinds of prosperity, material and spiritual. Why
then should one go to any demigod?
