Caru: Two young interviewers asked Prabhupada, “Have you seen God?” Prabhupada said, “What do you think? Before you buy gold, you should first educate yourself so you can recognize gold. So to know whether my answer is right or wrong, you need to know who God is and the qualifications for seeing Him. Do you know who God is and who is qualified to see Him?” They said no. “Since you don’t know, for better or worse you have to accept whatever I say. Will you do that?” “Yes.” “Then I have seen God.” That was powerful.
