The Seven Rays by Ernest Wood (Theosophical Publishing House, Adyar, 1925; later reprints in 1957 and 1976) is a classic work of Theosophical philosophy exploring the concept of seven fundamental energies or “rays” that shape human character, spiritual development, and cosmic order. Drawing on Hindu philosophy, esoteric traditions, and Theosophical teachings, Wood presents the rays as archetypal forces influencing psychology, ethics, and destiny.
