According to Osho, few follow Lao Tzu because his Advaita is an oceanic depth reached only by rare divers; it offers no worldly utility, power, or travel, only utter tranquility. People prefer Aristotle’s path, which gratifies ambition and yields visible results. Lao Tzu demands surrender of ego, status, and craving—he takes everything, offering only inner peace—so most flee.
Most people want quick power and rewards, but Lao Tzu asks us to drop all that for deep peace, so only a few choose him.
