According to Osho, there is no real contradiction: Lao Tzu and Krishna illuminate two poles of the same truth—act without the sense of doership. Lao Tzu says let action happen, like breathing, with no separate doer; Krishna says act fully but surrender the doer to God. Both dissolve ego, fit different disciples and moments, and culminate in effortless, witnessing action.
Both teachings say: do what needs doing, but drop the “I am doing” feeling so life can move on its own.
