Most of us read this as cheerful advice to be more flexible, but Rumi is describing something more unsettling—the dissolution of the self that does the resisting in the first place. When he says "let life live through you," he's not talking about passive acceptance; he's suggesting that the boundary between you and what's happening to you is an illusion worth questioning. A person in grief discovers this: at first they fight the loss, but somewhere in the middle of that dark tunnel, they stop being the one who grieves and become simply the place where grief moves through, and paradoxically, that surrender is where breath returns.
