According to tradition, light is the living substance with which God created the world. In recent years, particularly through the development of lasers, it has found an extraordinary field of research and application; light offers countless possibilities on both material and spiritual levels. Omraam Mikhaël Aïvanhov aims to bring us closer to the spiritual aspects of light: light as protection, as nourishment, and as a way to recognize humanity, nature, and God. Above all, he shows us that light is the only effective means to transform ourselves and the world. Omraam Mikhaël Aïvanhov.
