Mushin is one of the principles of Zen. It is a state of mind where the mind is not subjugated by any thought or emotion. In Mushin, ‘Mu’ means ‘empty’.Thus Mushin refers to an ‘empty mind’ in the sense that disruptions, fixations, dreads, and worries, are nonexistent and are no more a concern for the mind in daily life. In other words, it refers to evacuating the mind from all distractions, preoccupations, and all other chains of thoughts.
