Xeper is the divine principle which transformed pre-historic man from what we were millions of years ago into that which we are today. As I see it, Set is the first example of Xeper incarnate, which transformed him, Set, from once being a part of the Universe into becoming the First Principle of Isolate Intelligence within the Universe. What initially sparked Set's first act of Xeper, the Will to Come Into Being, is unknown.
Ah I see, this is my view as well.
