Mushin: Mind of No Mind

‎"Mushin" or "Wushin" is a state into which very highly trained martial artists are said to enter during combat. The term is shortened from "mushin no shin", a zen expression meaning mind of no mind. That is, a mind not fixed or occupied by thought or emotion and thus open to everything.
Mushin is achieved when a fighter feels no anger, fear or ego during combat. There is an absence of discursive thought, and so the fighter is totally free to act and react towards an opponent without hesitation. At this point, a person relies not on what they think should be the next move, but what is felt intuitively.
