My personal definition of a breakthrough is finding a new perspective beyond anything I thought possible. An epiphany. A new realization. A new awareness of being.
I have had experiences that would not quite push into the threshold of what some would consider a breakthrough. No machine elves giving high fives, no other worldly beings floating around telepathically giving me insights into the inner workings of reality, no jesters to amuse me or baffle me, none of that. The breakthrough for me could be simply letting all of that go and resting into a place where there are no thoughts, no colors, no amusements, no distractions, no emotion.
A place of complete and total awareness of being, aware of being aware. If that makes any damn sense. I am aware and it is only this awareness and this awareness alone.
I have had a similar experience but everything was white. In the whiteout, the emotion of love is present, but again it is just an awareness. No five ring circus side show.
I have had breakthroughs in life as well. Often spurred on by psychedelic breakthroughs. The breakthrough continued into my every day reality in a positive way. Integrating these powerful experiences into a working way in my life as best I can. Part of me thinks that the circus side show is the distraction, the side show is often seen as the breakthrough experience. It's fun to breakthrough into a crazy hyper-real world, but my definition of a breakthrough would be to bring something back with you to work with. Follow the sideshows into a infinite rabbit hole of distractions.
I have had so many experiences that would qualify as a breakthrough with the machine elves and all the rest of the madness and insanity in there. That place is freaking wild. These experiences were often so chaotic and jumbled up that I could not make heads or tales of anything. Often forgetting most of it and what I do remember just seems like someone took 10,000 puzzles with 10,000 pieces in each puzzle, threw them all in a pile, scrambled up all the pieces, laughs hysterically and tells me to put it all the puzzles back together. I just come out of it going WTF?!
I think each person should define breakthrough for themselves.
I like Minty Love's take on DMT and his take on this topic. I agree with what he says in this video ->
