So is there an eternal hell or not?

[Plenum]

I am guessing the closest would be getting trapped in a 'knot of fear'.

A la, post Maldek.

These entities were so traumatized by this occurrence that they were in what you may call a social complex knot or tangle of fear. Some of your time passed. No one could reach them. No beings could aid them.

Approximately six hundred thousand [600,000] of your years ago the then-existing members of the Confederation were able to deploy a social memory complex and untie the knot of fear. The entities were then able to recall that they were conscious. This awareness brought them to the point upon what you would call the lower astral planes where they could be nurtured until each mind/body/spirit complex was able finally to be healed of this trauma to the extent that each entity was able to examine the distortions it had experienced in the previous life/illusion complex.
