拳禅一如 joins the striking arts and Zen in four characters. 拳 is the fist, and in the names of the striking arts it stands for the art itself. 禅 is Zen, and 一如 is an old Buddhist word for one and the same, not two. In a dojo the fist stands for the body and Zen for the mind. So the phrase says a trained body and a trained mind are the same thing.
拳禅一如 is composed of the kanji 拳 (read ken) meaning "Fist" and represents the body, 禅 (read zen) meaning "Zen" represents the mind or spirit, and 一如 (read ichinyo) meaning "oneness".
A karate phrase in print by 1934 and the first principle of Shorinji Kempo, founded in 1947, made by putting the fist where the sword had stood in 剣禅一如, a phrase itself in print from 1916 for what the Zen master Takuan had taught the swordsman Yagyū Munenori three centuries before.
