i was thinking more along the lines of excessive pride/arrogance and narcissism where some people actually believe they are better then others.
I've been trying to locate anything Seth said about this type of pride and so far have come up with nothing worthy to contribute. On the Seth search engine, I found zero about narcissism. I suppose if I searched on ego I would come up with more than I could read. The closest my mind comes up with is idealism, which Seth does talk about, as well as its inflated relative, fanaticism. But your question has piqued my interest so I'll keep searching. Maybe just the right word combination on the search engine... but not all Seth related books have been catalogued as of yet.
With the rare spare time I've had lately, I've been reading and really enjoying
Dreams & Projection of Consciousness. Just today I came across some excerpts from one of the early sessions, 115. Since the Christ consciousness has come up in this topic, I thought it was interesting timing and also some new information for me. At one time Voidy Paul thought he remembered the crucifixion story being a "gift from F2" or something like that, and this also sort of fits in with what he thought he remembered. I can't find Paul's statement right now, but here goes. I'll add this to the "Seth on..." later.
Seth:
"As a brief byline here, I mentioned once the Crucifixion, saying that it was an actuality and a reality, although it did not take place in your time. It took place where time is not as you know it. It took place in the same sort of time in which a dream takes place, and its reality was felt undeniably by generations, and was reacted to. Not being a physical reality, it influenced the world of physical matter in a way that no purely physical reality ever could.
(See the 81st session for Seth's statements on the Crucifixion. This session and the 96th, among others, dealt much with the God concept, psychic gestalts, myths, etc.)
"The Crucifixion was one of the gigantic realities that transformed and enriched both the universe of dreams and the universe of matter, and it originated in the universe of dreams. It was a main contribution of that field to your own, and could be compared physically to an emergence of a new planet within the physical universe.
"The reality, the physical reality, of fire was such a contribution made by the physical universe to the universe of dreams. Physical man, observing fire, dreamed of it, thereby immeasurably enriching the universe of dreams. His discovery in the physical universe of domesticating fire was another such contribution to the dream universe.
"The ascension of Christ did not occur in time as you know it. It is a contribution of the universe of dreams to your own universe, representing knowledge within the dream universe that man was independent of physical matter ultimately."
@WindWalker thanks for the gnosis link. I read a bit about the gnostics a while back when I was starting my spiritual quest, but I think there is a lot more information available on the internet now.
