The translation of the book “The Great Triad” introduces the reader to the point of view of Rene Guenon, a well-known researcher of the Unified Spiritual Tradition in our country. The "Great Triad" refers to an esoteric concept from the Far Eastern tradition, particularly the Chinese; we are talking here about the triad "Heaven, Earth, Man", it is compared with other triplicities widespread throughout the world, made up of similar or different terms. The interpretation is carried out at all available semantic levels, and it is placed in the context of not only Eastern metaphysical teachings, but also those that existed in the West. Of particular interest in the book is the concept of man, which gives the entire discussion of this topic a special dimension. Without a doubt, it will be a useful, necessary book for all readers interested in the topic of self-knowledge and transformation.
