Zanshin means “the remaining mind” and also “the mind with no remainder.” This is the mind of complete action. It is the moment in kyudo (Zen archery) after releasing the arrow. This is “ Om makurasai sowaka” in oryoki practice and drinking the rinse water. In shodo, it is finishing the brush stroke and the hand and brush moving smoothly off the paper. In taking a step, it is the weight rolling smoothly and the next step arising. In breathing in completely, it is this breath. In breathing out completely, it is this breath. In life, it is this life. Zanshin means complete follow through, leaving no trace. It means each thing, completely, as it is.
When body, breath, speech and mind are broken from each other and scattered in concept and strategy, then no true action can reveal itself. There is only hesitation, or trying to push oneself past hesitation. This is the mind of hope and fear, which arises because one is trying to live in some other moment, instead of in the moment that arises now. One is comparing, planning, or trying to maintain an illusion of control in the midst of a reality which is completely beyond control.
