Evelyn Underhill (1875-1941) regards mysticism as the core of religion. All religions include various dimensions: scripture/ mythology, doctrine/ philosophy, ethics/ law, social/institutional features, ritual, material aspects, and personal and communal experience. For Underhill, personal religious experience inspires and influences the development of these other aspects of religion—the heart of which is mysticism. Underhill asserts: “The mystics are the pioneers of the spiritual world” (4); “Mysticism is the art of union with Reality”.
