Different methods of moving are used in different schools. Yin-Yang, or
"In-Yo" in Japanese, is female-male, dark-light, right-left. Musashi advocates this "level
mind" kind of walking, although he is emphatic about the significance of these parameters - issues
of right and left foot arise in the Wind book of Go Rin No Sho. Old Jujitsu schools
advocate making the first attack with the left side forward.
