This is and extract from the forward of a book where Jun’ichi Arai is talking about the work of Yoshiko Jinzenji.
Works of concentrated strength and seeming artlessness have a spirit of impromptu prayer that draws on the energy of nature. Impromptu creations can come about only through such prayer. There is no greater power on earth than that of prayer invested with the whole heart and mind and strength. Such prayer is life itself.
