Don't manufacture duty. Duty is already there. Take it up and be happy. We are doing that. How we say, "Here is duty"? We may be not very much learned, but we take the simple thing, that's all. Our duty is to carry out the order of Krsna. Caitanya Mahaprabhu confirmed it, my Guru Maharaja confirmed it, we accept it. Why should we be unnecessarily very learned man? Eh? There is a Bengali proverb, uthi chala kel balai derhi[?]: "If one is too much intelligent, he should be hanged." [laughter] [laughs] Over-intelligent. Krsna may give me the good intelligence that whatever I have been able to do or what I am going to, let me be fixed up in my faith in Krsna, that's all. I don't want anything. Why shall I create my duty? Duty is already there.
