According to Osho, in Lao Tzu’s vision sadhana has no real place: whatever is gained by practice becomes mere habit, touching only the body-mind periphery, not the innate nature that already is. Truth is uncovered through non-doing and letting go. Practices are at best provisional crutches for doers—used until exhaustion ripens into dropping all effort, whereupon realization is instantaneous.
Stop trying to make truth through exercises; your real self appears when you finally drop all effort.
