Sirius is the Hidden God or "the sun behind the sun". As the moon reflects the sun, so does the sun reflect Sirius. This concept was expressed in The Book of the Law when Crowley wrote "The Khabs is in the Khu, not the Khu is in the Khabs." The word Khab means star while Khu refers to light. What is being taught here is that collective "wisdom" often assumes that the stars emanate light. The truth of the matter is that the stars are in the light and are merely reflecting it.
