This is where I'm perplexed. I mean, does all growth and change happen in "illusion" only or can it also happen in the "essence"? I currently tend to think that the absolute doesn't change or grow. The C's say "Consciousness is the absolute, the center point." So, I think consciousness in its pure essence doesn't change or grow.
Yeah, "timelessness" sounds like "death" (freezing of life/being) from a certain (and widespread?) point of view. Maybe it's mainly our ego which thinks like that. The concept of "dying before death" can be closely related to this, and seems to be a very central point of "work on self". Apparently, when we overcome it, we'll get rid of "fears and desires", or of their control on us, at least.
