According to Osho, failure is inevitable in the world because 'world' means our unconscious, dream-like state; whatever we gain here is illusory and actions done in stupor go wrong. Intoxications—of power, wealth, ego—keep us asleep, so apparent successes cannot fulfill. Only awakening—through watchfulness and meditation—ends this cycle by dissolving the dream and revealing reality.
We fail because we act like sleepwalkers chasing dream-things; wake up and be aware to stop stumbling.
