Mushin (無心; Japanese mushin; English translation “without mind”) is a mental state into which very highly trained martial artists are said to enter during combat. They also practice this mental state during everyday activities. The term is shortened from mushin no shin (無心の心), a Zen expression meaning the mind without mind and is also referred to as the state of “no-mindness”. That is, a mind not fixed or occupied by thought or emotion and thus open to everything. For the origin of the mushin concept, see Muga-mushin. It is somewhat analogous to flow experienced by artists deeply in a creative process.
oh well, Never Mind.. ;-)
