In his book Zen Spirit, Christian Spirit: The Place of Zen in Christian Life (Continuum), Father Robert Kennedy shares his discovery that the interplay of traditional Christian beliefs with the study of Zen leads to a new way of being Catholic by rooting faith in the whole person and not just the head. He learned firsthand that Zen is not a religion but a way of viewing life that can enhance any faith. Zen leads to self-knowledge, deeper prayer, and a livelier service to others.
