Library JournalMost Western treatments of Taoism deal with its philosophical aspects or with meditation and health practices. Taking a different approach, Olson, a Taoist practitioner and author of several other works on the topic, translates and comments on three classic texts dealing with immortality. The Immortals presents a case for accepting the possibility of immortality. The Jade Emperor's Mind Seal Classic transmits in mystical language the wisdom that could lead to spiritual transformation and immortality. Finally, The Three Treasures of Immortality puts the concepts of the Mind Seal Classic in more concrete terms, discussing how the three treasures-essence, energy, and spirit-can be developed for spiritual transformation.
