This is what I say Locke is on LOST....
"The Akh, Khu and Sahu:
Before moving on to further discussion of ritual there are several other Ancient Egyptian concepts that will aid you as you develop in your practice. One is the Akh, sometimes referred to as the Khu. This term means
"transfigured spirit," the "shining one" or "luminous one." Beyond the Ba this spiritual body is one's higher spiritual self, the immortal spirit or, as the Ancient Egyptians explained, that part of the person that is "imperishable" (West 1985.65).
Egyptologist A. Lloyd explains that the Akh "differs in character from all the other entities as it represents the total person in
a state of beautitude and power beyond the grave, i.e., nothing less than the deceased reconstituted and placed in all respects in a position where he can function according to the Egyptian concept of the blessed dead" (Lloyd 1989.117-133). From here the highest state being, known as Sahu to the Ancient Egyptians, may be attained. Sahu is, in essence, a union with the Neteru; a merging with the divine. This is the ultimate goal of the magician following the Ancient Egyptian path."
