This new edition is now volume I in the trilogy that describes the fundamental philosophy of the esoteric system of Vibrational Sound & Color, which Elias De Mohan during the 1970's was instructed to create by Djwahl Khul. Volume I describes the esoteric philosophy of sound, color and breathing and the exercises of the Seven Rays. In this new edition Elias and Raphael De Mohan has taken the pioneering and esoteric system of Vibrational Sound & Color a step closer to the Age of Aquarius. The system is practical and designed to the experiential process of transformation of the personality and expansion of soul consciousness. It offers step-by-step exercises in diaphragmatic breathing, vibrational sound, and color awareness. Our breath supporting the vibrational sounds of our unique voice is paramount in expressing and releasing who we really are and is the basis for experiencing the vibrational energy fields of the soul. Progress on the path comes as one confronts, accepts and resolves the issues of the ego-personality; present and past life issues and fragments - for they are what our soul wants us to experience and they are the very stepping stones of evolution. It is possible with constant practice day-by-day, as shown in this book, to reach the level of experiencing the vibrational energy field of the soul.
