An atheist or an unbeliever, he must be a first-class foolish man. There is no other reason that one can deny the existence of God. It is very simple reasoning, that who has given you the power to talk and who, if he withdraws the power from you, then what is your value? How can you boastly say that "I don't believe in God"? This very power of speaking is the proof that there is the greatest authority who gives you everything.
Therefore the Kṛṣṇa conscious person, he knows that "Everything, whatever I have got, it is not my . . . under my control. The controller is different. I am feeling . . . I am simply using it. I am talking. This is my hand; I am working. But if the power of working is immediately withdrawn—it is paralyzed—have you got any power to revive this working power of this hand? No. You have not. One hand will work; another hand will stop. Who stops?" These things are to be taught. How can I deny?
There is something. If I don't believe in God, but I must believe some power beyond me which is controlling me every step. Either call it God or anything, nature, but there is a controlling power. You have to admit. How can you deny it? Therefore anyone who denies the existence of God, he is a foolish man. He is not very intelligent man. No intelligent man will deny.
