If you do not entertain self-referential thoughts of gain and loss, then in Chan you are "one with nothing to do." Nothing to do does not literally mean doing nothing. Rather, it means your mind is unobstructed when you engage in any task. 心中不存得失想，便是世間無事人。無事不是沒事 做、不做事，而是做事、任事之間，心中沒有罣礙。 - Master Sheng Yen
