According to Osho, doubt is a purifying fire: use rigorous reasoning to question every belief, not dismissing negation as ‘sophistry.’ Follow doubt to its limit—where intellect exhausts itself and falls silent; that very silence opens the door to mystic knowing. Suppressing doubt breeds irrationality; honoring it prepares the ground for authentic insight and meditative realization.
Keep asking questions until your mind grows quiet; in that quiet, real understanding appears.
