Part 2 of the gospel of truth
This ignorance of the Father brought about terror and fear. And terror became dense like a fog, that no one was able to see. Because of this, error became strong. But it worked on its hylic substance vainly, because it did not know the truth. It was in a fashioned form while it was preparing, in power and in beauty, the equivalent of truth. This then, was not a humiliation for him, that illimitable, inconceivable one. For they were as nothing, this terror and this forgetfulness and this figure of falsehood, whereas this established truth is unchanging, unperturbed and completely beautiful.
The duality of tbe demiurge (universe mind) creates the seperation which makes us think we are all seperate people. Interestingly the fog could imply (atoms particles). The gnostics were very clever due to understanding the fabric of the universe (its simplier than you realise).
The matter is limited (temporal) hence forgotten its true substance. The matter is form in truth its substance is eternal. The terror of seperation and forgetfullness is nothing like the established truth. The truth is unchanging, matter is always changing.
