The Great Central Sun, also called the Great Hub, is the center of cosmos; the point of integration of the Spirit/Matter cosmos; the point of origin of the physical/spiritual creation; the nucleus, or white fire core, of the Cosmic Egg. (The God Star Sirius is the focus of the Great Central Sun in our sector of the galaxy.) The Sun behind the sun is the spiritual Cause behind the physical effect we see in our own physical sun and all other stars and star systems, seen and unseen, including the Great Central Sun.
