The text outlines a model of the universe based upon the forces of Power, Love and Wisdom. Associated with each is a path, a ray, that we can travel spiritually and evoke energetically. Known as the Straight Line, the Bent Line and the Crooked Line, each offers different opportunities of magick, knowledge and initiation. Each ray is associated with a race of spiritual entities with whom we can partner, including the angels, faeries and creatures of flesh and blood, including the animal powers and ancestors.
