So Dhṛtarāṣṭra said that "I know that what I am planning, that is not good. I know Kṛṣṇa—the Supreme Personality of Godhead. And He has requested me. But I tell you frankly, I cannot do without it. So when Kṛṣṇa will be pleased upon me, I may be."
So this is the position of the materialistic person. A materialistic person knows that he is sinful. A materialistic person knows that whatever he is doing is wrong, but he cannot check. Just like the thief. A thief knows that if he commits stealing, he will be arrested, he will be punished. He knows. Because he heard from lawbooks, from other sources, and he has also seen that a thief is arrested and he is taken by the police for being punished. So we have got two kinds of experiences: by hearing and by seeing directly. In Bengali it is called, dekhā-śunā. In India it is called. The two kinds of experience: one by seeing, practically experiencing, hand to hand; another by hearing. So one who is intelligent, he gets his experience simply by hearing from the right source. That is nice.
