Pulse
the channel through which the body’s tide moves, and the reading of it
One character holds both the vessel and the beat that travels it: 月 in its flesh sense, set beside 派, the branching of a watercourse — a body described as a river system. In classical medicine the pulse is not merely counted but read, taken at three positions on each wrist, its depth, speed and shape a sentence about the whole body rather than a number. The word did not stay in the body. 山脈 is a mountain range, the branching of stone; 脈絡 is the thread of an argument, the through-line a reader is asked to follow. Anything that branches and carries can take it. To take the pulse is to listen to a rhythm that was running long before, and will run long after, the listening.
