This volume in the Ario-Hermetic Rune Magic series by Peryt Shou focuses on sound-magical tantra. The studies contained in this book may guide the esotericist to penetrate the inner connections of the universe by means of his own hermetic investigations. The ritual laws of logos (creator language), numerus (number) and gesture, as treated in this book on the basis of the ancient mysteries, will be of great benefit to him. In particular, some skill in the numerical analysis of the terms will create entirely new research material. Just as the laws of number are universal, so too are the laws of thought, if it is in harmony with them. Such thought is able to lift the curtain to the spiritual worlds, setting the stage for practitioners to enter the heavenly spheres and dwell in them forever! Peryt Shou (born Albert Schultz) was a German occultist, pagan revivalist and theosophist. During the course of his career he authored some forty books, most of which have been forgotten and lost in obscurity. However, he remains one of the most important esotericists of 20th-century Germany, mainly because his works, although obscure, were nevertheless extremely influential on other German occultists of the day. Shou also taught "practical mantracism" as an occult practice to unlock the powers of "vocal breath" by chanting specific combinations of syllables. Mantras were an important part of his yoga system, which also involved controlled breathing and visualisation techniques. As an occultist, Shou employed "mantracistic prayers" to allegedly develop extrasensory abilities such as mind control and telepathy.
