There is no difficulty. Simply one must be sincere, not sinful. But a sinful man cannot understand Him. The sinful man, he will say, "Oh, Kṛṣṇa is also man. I am also man. Why I am not God? He is simply God? No, I am also. I am God. You are God, you are God, every God." Just like Vivekananda said, "Why you are searching after God? Don't you see so many gods are loitering in the street?" You see. This is his God realization. This is his God realization. And he became a big man: "Oh, he is seeing everyone God."
This foolishness, this rascaldom, is going on all over the world. One does not know what is God, what is power of God, what is meant by God. They are accepting some rascal as God. As nowadays, that is going on. Another rascal has come. He is also declaring himself God. So it has become very cheap thing. But they have no brain to think that "I am claiming God; what power I have got?"
So this is the mystery. This is the mystery. Without becoming devotee, the mystery of understanding God is not possible. And Kṛṣṇa has said in the Bhagavad-gītā how one can know Him. Bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ (BG 18.55). Only by devotion, simply. He could have said, "By high, topmost knowledge" or "By yogic process" or "By acting, becoming a very great karmī, worker, one can understand Me." No, he has never said, never said. So the karmīs, jñānīs, yogis, they are all rascals. They cannot understand Kṛṣṇa. All rascals. Karmīs are third-class rascals, the jñānīs are second-class rascal, and the yogis are first-class rascal. That's all.
