According to Osho, leaders like Moses, Mohammed, and Mahavir are 'practical' because they fit and compromise with your present mind: they refine behavior, make you virtuous and efficient, but leave your basic dimension unchanged.

Some teachers tidy up your habits, while Lao Tzu rebuilds you from the ground up.
