According to Osho, Lao Tzu is rarely accepted because his vision is ocean-deep and demands inner loss, not gain. The world prizes boat-builders like Aristotle who offer usable formulas for power and travel, while Lao Tzu offers only peace and arriving at oneself. Ambition flees a master who 'takes everything.' His words belong to the kind understood only after one is transformed—hence few can receive them.
People chase power and results; Lao Tzu asks you to drop everything and be still, which few want or can understand until they change inside.
