There is a great difference between ordinary madness and divine madness. Although it is great, it is very subtle. There is something similar and something absolutely different.
The ordinary madness means you have fallen below the mind — but you have fallen out of it. The divine madness means you have gone beyond the mind — but you have gone out of it.
Falling below the mind and going beyond the mind have one similarity: both are leaving the mind behind; hence, the madman and the sage in some way look similar, but their difference is great. To be beyond the mind means to be in silence, utter silence. To be beyond the mind means you become the master of the mind. To fall below the mind means you become a slave of the mind. All the whimsical ideas of the mind you have to obey; you don't have any control over your mind.
The man who has transcended his mind is in absolute control of his mind. He uses it when needed, and he stops using it when it is not needed; mind becomes an instrument in his hands.
But for the ordinary man the situation is very sad. He becomes an instrument in the hands of the mind.
OSHO
