Maybe you have too many expectations about what "this" or "awakening" or "enlightenment" is. Your brain/mind can seem to "come back" and "claim" an experience; however you perceive
and label such an apparent happening is this too. There is nothing that is not this. That's what an "ah ha" moment means, and why it's so amusing. What you are looking for is everything, just the way it is. It is occluded by its omnipresence. It's so simple, your mind can't possibly believe it's so obvious.
Moments of peace are great, but they aren't especially "this". They are this in yet another guise. Doubt, resistance, fear - this in an egoic guise. However, when "this" is "realised", there seems to be less resistance, doubt and fear - but this isn't "let's make a deal". There are no guarantees about what the quality of life will be, in the story that seems to unfold, if wholeness is apprehended. The only guarantee is that whatever it is that seems to be happening, thought, or felt is this. EVERYTHING is what the seeker searches for. You can stop looking. THIS IS IT!
I've always liked the analogy of nonduality as a film; the characters have interesting lives, but cannot change what happens; and yet they are light itself; what we truly are is likened to the light that makes the projections possible. Well, let's play with that. What if the characters unravel reality and hop off the screen, no longer slave to the film and script? That's explored in Woody Allen's Purple Rose of Cairo. The characters that remain argue about who is the most important character. One bumbles on, and exits in a fluster; he's not due until the third reel. The ego and its imagination loves the idea that it has absolute freedom. Enjoy.
