The Empty Boat (Zhuangzi)

In the twentieth chapter of the Zhuangzi ('The Mountain Tree'), the parable of the empty boat teaches: if a man crossing a river is struck by an empty boat, he feels no anger — but if the boat has someone in it, he shouts in fury. The collision is identical; only the perception of a self inside changes the response. Zhuangzi's instruction is to 'empty your boat' (xū zhōu 虛舟) — to act in the world without the burden of a fixed self that others can collide with. This is wu wei carried to its deepest implication: not merely effortless action but the dissolution of the agent who would claim the action as 'mine.'
