Light Sitting in Light: A Christian's Experience in Zen by Elaine MacInnes recreates the spiritual journey of a woman who has been invested as a Zen master or roshi, an old teacher. She has studied in Japan and now lives in England.

MacInnes sees Zen as a discipline that can enrich the lives of Christians. She writes about the art of silence, the practice of sitting meditation, the silencing of the ego, the use of koans, and the therapeutic value of a practice. Her favorite teacher, Yamata Roshi, taught her that prayer is "light sitting in light." MacInnes believes that her study of Zen has deepened her prayer life and taught her how to commune with the immanent God. The author predicts that eventually Zen will be integrated into the institutional church. Her book helps build bridges between Christianity and Zen Buddhism
