A young man went to Nagarjuna. And he said, "I have started experiencing god. His face is in front of me. I close my eyes, god smiling faintly stands before me, I really enjoy it." Nagarjuna said, "You do one thing." Nagarjuna was a rough carefree sadhu, an extraordinary sadhu. A man just like Gorakh. He said, "You do one thing, then we will talk about this experience. You sit in the small cave facing us and think for three days that I am not a man, I am a buffalo." He said, "What's the matter? Why should I think this?" Nagarjuna said, "If you want to be in contact with me and you want to understand then this will have to be done ??? a small experiment. After doing it I will reveal the secret." The man went on sitting for three days. He was a stubborn man. For one who has dragged the face of god near, what's difficult in a buffalo? He got totally into it. For three days he didn't sleep, didn't eat,
