The Typhonian deity Seth was once worshipped in Ancient Egypt. Followers of later schools obliterated Seth’s monuments, demonised and neglected his cult. A possible starting point in the quest for the ‘hidden god’ is an examination of the life of Egyptian King Seti I (‘He of Seth’) also known as Sethos. When looking for an astral temple that included all of the ancient Egyptian gods and goddesses, the temple of Seti I proved itself worthy of examination. Many secrets began to reveal themselves. The essence of the real philosophy of the Sethian and indeed what Satanism is, stems from the authors astral wanderings in this temple. The temple is a real place, and like any temple no part of its design is accidental. It is a record in stone and paint of the Egyptian wisdom. It also fits quite well with the Thelemic mythos and tells lots of interesting things about the ancient Seth cult – if you have the eye to see it.
