Once I had to give some money for a devotee to go to Taiwan. I didn’t like that devotee because he would not cooperate, so I refused. “No, Prabhupada, I won’t give him any money.” Srila Prabhupada said, “I will give him.” I said, “Prabhupada, you’re wasting your money on this man,” and we discussed this. Finally I got angry, stood up and said, “I quit, I quit, I quit.” Srila Prabhupada said, “I will also quit. Now sit down.” Then after I cooled down, I said, “I’m sorry Srila Prabhupada that I got so excited.” He said, “That is good you are enthusiastic.” It was not a bowl of cherries to be around His Divine Grace. It was not easy. He was the acharya and he had to set the standard.
