Thanks, somehow that doesn't sound as significant as "EGO death"!

I think it partially became popular because the ego can panic and feel like its literally dying because our usual sense of self is being expanded, and that can be extremely scary ~ especially when the ego goes further towards full dissolution.

So "ego death" describes how it can feel to those not used to, at least.
