LEARNING HOW TO BE. The work of A.H. ALMAAS, since more than forty years, aims at diffusing the learning of how to be, not only for medical and psychological professions. Two of his twenty-two books have been already translated and published in French, and we plan to publish them all in this bilingual collection. We hope that in a future as near as possible, these works will be part of the basic studies library of all human beings seeking to cultivate themselves, of any doctor, psychiatrist, psychoanalyst, psychologist, therapist or coach. We hope this because the efficacy of therapy is also proportional to the patient and therapist’s openness of consciousness, whatever the techniques and methods used. A. H. Almaas, still very little known in France in 2019, has been nicknamed the Einstein of psychology and spiritual development, for he renewed the field’s paradigm, as Einstein renewed the theoretical physics paradigm. A nuclear physicist, psychologist, psychoanalyst and founder of a psycho-spiritual school comprising of, to date, more than four thousand students and teachers in the USA, Canada, Europe, and Australia, he implements the study and practice of psychology and spirituality with the same precise scientific analysis as when analyzing the intimate physical components of matter. His method, the Diamond Approach, is based on the direct experience and exploration of common and expanded states of consciousness, and uses the Enneagram as one of its tools. It is a cognitive psycho-spiritual approach, allowing for a progressive understanding, then an expansion of consciousness, from the extreme narrowness of pathological condition, to the opening of ordinary consciousness, to enlightened consciousness, to universal consciousness. This book is the third publication of the Bilingual English-French Collection of the Diamond Approach: Original version in English : DIAMOND HEART BOOK 1, French translation of Gérard BATTAREL, Eme LE CAVALIER and Michel COSTELLE : CŒUR DE DIAMANT LIVRE 1.
