The pure source that the demiurge imitates, never given a name.
In the sermonsch. 4
The snake's sermons in chapter 4 speak of lost souls “further losing their name of the nameless one; from them pours itself, of itself.” When the demiurge calls himself “the first and only God,” the sermon calls it “a blasphemy against the nameless purity and its indescribable holiness.” Of the place the lost came from it says, “What ought to be is always being, and of itself is complete light.”
Among the Euclidsch. 16
The Euclids argue over it. The Northern tribe does not see “an absolute nameless simplicity as emanator and ” believing instead in an infinite one that only a few may unlock. All the Euclids acknowledge the demiurge; they differ “in the manner and kind of essence of the nameless one, and in solution.”
Note: the nameless one belongs to the Fullness, and is what the demiurge imitates.
