Master Koretoshi Maruyama has over the years studied and taught a variety of alternative healing arts, as these are essential to any martial arts practice. Already O-sensei Morihei Ueshiba had stressed the healing aspects of Aikido and had integrated exercises for health into the warm-up exercises, as well as, for example, turning 'immobilisations' into stretches for health.
Healing arts, working through the channeling of Ki as practised and taught by Haruchika Noguchi (Seitai or yuki), or as in Reiki (Mikao Usui), or gentle body manipulation as in Soutai Hou (Keizo Hashimoto), have been the essential ingredients Maruyama Sensei has drawn on to distill out his own art (formerly called YUKI), which is most suitable as a foundation practice for Aikido Yuishinkai, as well as a very effective healing modality.
Maruyama Sensei has named this new practice "Shin Dou" or commonly called "Shindo". In the Japanese calligraphy a number of different kanji are used to express Shin: ＝ 振 vibration, wave, but also 身 body, and another 心 for mind, heart, spirit; and Dou 道= way or 動 movement, etc.). Maruyama Sensei has chosen
which gives a hint of the basis for the art. One needs however to see and feel the process in order to understand.
