Answer from Master Kosen
Zen is the specific realization of the dimension of Buddha which exists in ourselves. But everything in the universe is only a question of a fulcrum, to exist, to be revealed, everything must rest on a fulcrum. For example, movement rests on immobility, that is why in zazen we should not move. During zazen, if we want to discover the inner world, the world of the mind, the fulcrum is the body.
