According to Osho, madness literally means going out of the mind, and it has two directions: falling below the mind through shock and breakdown—irrational, unstable, an escape from pain—and rising above the mind through deep meditation—a ‘divine madness’ (masta, paramhansa) whose paradoxical behavior reflects a higher logic and profound beauty. Both lie outside ordinary mind; one is pathology, the other transcendence.
Madness is leaving your usual thinking: you can fall down after shocks or rise up through meditation into a wise-but-weird freedom.
