This work by the well-known scholar and occultist Israel Regardie contains the fruit of the experience and knowledge gained in a whole life of study and practice of occult techniques. In particular, the author highlights the practical methods through which it is possible to come into contact with occult, internal and astral forces, which allow you to develop the faculty of operating magically. The techniques presented belong to both western and eastern culture, revealing a surprising identity of methods and purposes. The author then examines the magical techniques best known to us, such as divination, geomancy and astrology, but also the Jewish Kabbalah, the forms of oriental meditation, the healing techniques by means of thought and vital energy. This work is therefore an excellent compendium of the theory and practice of magic, a matter of great charm and wonderful results, but also littered with unknowns and dangers; it is therefore of precious use to those who undertake the “magic way”, since correct information and gradual and adequate preparation are the fundamental basis for the construction of their evolutionary path, capable of transforming the human being into a “magician” in the truest and deepest sense of the word.
