David; there is an old gnostic quote I’m trying to remember that goes something like:
“If you bring forth that which is within you it will save you; but if you deny that which is within you it will destroy you.”
I know this is not the precise version of the quote; but my sense of it is that it may be saying something similar. From your understanding are we talking about: “the other in you; like the shadow; or is it a denied wish or talent that has not been given it’s voice or both; perhaps suppressed from the internal Dragon power that must be faced, assimilated, or integrated as you were just mentioning?
Here is an addendum link I am adding that contains a number of related quotes which include God as well as the above. Carl Jung concerning this Thomas Gospel quote.
