Make your strength equal all over the body. Your muscles must be agile. They must be able to contract, stretch, relax and become firm in harmony with each other. Your strength must come from inside you and the radiate out. When moving, slowness excels over speed. Be relaxed rather than impatient. Your movement should be slight, but your spirit should be full.
