1. Govardhana lifting is the God-test

    Acyutananda: "In India, there are many svamis who claim themselves to be Krsna. How to detect them?"

    Prabhupada: Hmm? Many svamis…?

    Devotee: Claim to be Krsna. How to detect them?

    Prabhupada: Let them prove that he is Krsna. If you are foolish, then they will accept. If you are intelligent, then you'll ask him, "First of all lift the Govardhana Hill, then you become Krsna. Otherwise you are rascal, I kick you on your face." [laughter] This is our version. We do not accept these rascals as Krsna. We want to test, first of all, that you are Krsna. Why should we accept a rascal as Krsna unless he proves himself that he is Krsna? Krsna lifted Govardhana Hill when He was seven years old. What he has done that we shall accept him Krsna? Don't be foolish. First of all let him prove that he's Krsna. Test him. Then accept.
