"Om is formless, but Krishna has got a beautiful form, enjoying. And we are addicted to beautiful form. Why something which is not beautiful? Krishna says in the Bhagavad-gita, "I am omkara." So in one sense omkara and Krishna are the same. But I can see Krishna very beautiful and so many things, but I do not see in omkara that thing. Therefore my preference should be to Krishna."
