Is every great spiritual tradition only part of the truth? Yes, says Raphael Raven in his book, The Four Kinds of Enlightenment: Love, Unity, Emptiness, and Tao. Raven distinguishes four kinds of mystical experience: - Love as in Bhakti mysticism, most of Christian mysticism and Sufism: the enlightenment of emotion - Unity, which comes with Advaita Vedanta, some trends of Sufism and Christian mysticism, Kabbalah, Neo-Platonism, and more: the enlightenment of intuition - Emptiness (absolute transcendence) as in Theravada, Tibetan Vajrayana, and other schools of Buddhism: the enlightenment of understanding - Tao (divine beauty), as seen in Taoism and Zen: the enlightenment of perception In a comprehensive and unbiased understanding, Raven shows how all are really complementary and can form an important framework for any spiritual seeker. The Four Kinds of Enlightenment is truly a guiding light for the soul. Raphael Raven has been a spiritual seeker since his youth and became an independent scholar and philosopher of mysticism. The Four Kinds of Enlightenment is his first book.
