According to Osho, only a 'madman' can become a Buddha—the so‑called sane can at best become Buddhists or Christians, not Buddhas or Christs. This 'madness' means the guts to step beyond social logic and philosophical mind-games. Philosophers hesitate or cling to rules; enlightenment demands a fearless, outrageous leap into direct experience. Hence: a madman, yes.
Yes—Osho says waking up like a Buddha takes brave, crazy courage, not neat, safe thinking.
