If fifty percent of all persons become enlightened, does it mean that fifty percent will have to become idiots?

According to Osho, the question arises from misunderstanding polar balance. Intelligence and stupidity are opposites, but enlightenment has no opposite; it is the transcendence of both knowledge and ignorance, happiness and misery. A genius is no nearer than an idiot—anyone can 'jump' beyond duality through courageous risk. Therefore, even if many awaken, no compensating stupidity is required; enlightenment belongs to a different dimension altogether.
