Otz Chim is a practical exploration of the magic of the Kabbalistic Tree of Life, the glyph which concentrates the essence of magic and mysticism within the Western Mystery Tradition. English alchemist and sorceror Gary Nottingham introduces the symbolism and imagery of the ten Sephiroth and twenty-two paths of the Tree, including their appropriate colours, scents and tools. Lesser-known aspects of the Tree are also included, such as the angels associated with the paths, their seals and invocations. This is a manual of practical Kabbalah, and included in the rites are the Lesser Banishing Ritual of the Pentagram, the Middle Pillar exercise, the Malkuth Temple, and the Massa Aborum Vitae (The Mass of the Tree of Life), a previously unavailable rite based on the aspects of the Tree and used by the author's ritual magic group. The author provides an ideal introduction to practical Kabbalah that will appeal to students and practitioners of ceremonial magic, the grimoires and western esotericism.
