Light Waves continues the themes of Morita and Naikan psychotherapy found in David Reynolds' highly popular Constructive Living and The Quiet Therapies: Japanese Pathways to Personal Growth. A book of reflections -- inspired in part by the Denkoroku, a work written by a Soto Zen monk -- Light Waves will appeal to readers of any faith. It reiterates the spiritual importance of everyday life and encourages readers to experience whatever reality presents and do whatever needs to be done moment-by-moment. Thought-provoking puzzles, designed to fine tune the mind, appear throughout.
