The Advent proposes and describes a new category of perception: 'vibratory awareness', beyond thought, feelings or instinct, by which all kinds of absolute questions are answered. This awareness itself thinks, organizes and loves. It balances, neutralizes and heals human problems, and relates man to the divine. It has been described in many scriptures, as, for example, divine breath, it is innate in every human being, though unconscious for most. It is known as enlightenment, Self-realization, second birth or mukti and incarnations who have come on this earth at different stages in human evolution have prepared the setting for its manifestation on a mass scale, as the phenomenon of 'collective consciousness'. Readers can personally verify the existence and validity of this awareness, indeed, many already have. Evidently, the one who has introduced this breakthrough leading man to his evolutionary maturity, is a truly unique being. H.H.
