Hitsuzendo is the way of Zen practice with brush and ink (calligraphy). Using the brush is first practised with simple lines and shapes, allowing the disciple to experience how the brush is guided by his life energy from his centre while he exhales. The act of writing becomes purposeless, independent of any will-power. Body, mind, brush, ink and paper unite and become indistinguishable from the act itself.
Hitsuzendo was developed by Omori Sogen Roshi in Japan as a way of Zen practice. Hitsuzendo is practised on the ground, using a large brush and ink, usually on newspaper. This way, the whole body is used to guide the brush, in contrast to writing at a table.
Kuwahara Sensei teaches Hitsuzendo by agreement.
