Throughout the whole world you study big, big men, they committed mistake. Hitler committed mistake. Gandhi committed mistake. Churchill committed mistake. Because "To err is human." However big you may be, you cannot avoid mistake, because you are not liberated.
So these are the signs of becoming perfect man: that he does not commit mistake, neither he is illusioned. Illusion means to accept something as something. That is illusion. Just like we are accepting this body as myself. If you ask me, "What you are?" "I am Indian. I am brāhmaṇa. I am this. I am that." So what are these? These are all bodily concept of life. This is illusion. Illusion means I am not this body. You have got experience when a man dies, his relatives and children cry, "My father is gone." But actually the father . . . the sons who knew the body of the father as the father, that was illusion. Now, after death he is coming to understand that, "My father is gone." Why your father is gone? It is lying there. The same hand, legs, heads, coat, pant, everything is lying there. Why do you say that your father has gone away? That means the real father he has never seen. He has seen the illusion of his father. This is called illusion. Is there any doubt? I am seeing you. What I am seeing, you? I am seeing your body, your shirt, coat, pant. That's all.
