Walking meditation. Although its meditative aspect is of prime importance, kinhin also serves the purpose of moving one’s legs after a long period of zazen, thus making physical problems unlikely. Hands should be held in the shashou position. Some schools of Zen perform kinhin extremely slowly while others do it rapidly. It has become traditional, in North America at least, to combine the two: kinhin begins very slowly at first and then switches to a brisk pace (the change is marked by an audible signal).
