According to Osho, what prevents enlightenment is the very desire and ambition to attain it. The master’s ‘favor’ of blocking you is a device to frustrate seeking so the grasping ego drops. When the urge to become somebody—even enlightened—relaxes, silence and awareness reveal themselves. Enlightenment happens when striving ceases, not as an achievement.
You miss enlightenment by trying to get it; when you stop chasing, it appears on its own.
