The pain of ego death (enlightenment) is the highest emotional pain a person can ever experience. After that, there is no more pain. It doesn’t happen instantly, it’s a process, but if it was collapsed into a single moment, the intensity of pain would be out of this world. I’m not even sure the body would be able to take it, although it probably would, the body is a miracle.

There is no higher pain, so in enlightenment there is no more pain, only happiness and serenity.

The pain of ego death is the accumulation of all the pain one has been carrying with them in the unconscious since the early childhood. The bliss coming afterwards is but the mirror to that pain, the freedom from it. It’s not new pain, it’s the existing pain coming up to the level of consciousness. Experiencing it all in once is unthinkable, but it can be experienced, and one can become absolutely and totally free from all emotional pain.
