"You know that in all tombs there is always a false door?" Renisenb stared. "Yes, of course." "Well, people are like that too. They create a false door - to deceive. If they are conscious of weakness, of inefficiency, they make an imposing door of self-assertion, of bluster, of overwhelming authority - and, after a time, they get to believe in it themselves. They think, and everybody thinks, that they are like that. But behind that door, Renisenb, is a bare rock … And so when reality comes and touches them with the feather of truth - their true self reasserts itself."

To say a man does mad things because he is mad is merely unintelligent and stupid. A madman is as logical and reasoned in his action as a sane man — given his peculiar biased point of view. For example, if a man insists on going out and squatting about in nothing but a loin cloth his conduct seems eccentric in the extreme. But once you know that the man himself is firmly convinced that he is Mahatma Gandhi, then his conduct becomes perfectly reasonable and logical.
