I appreciate that you find freedom in your personal belief system, and I'm happy for you. But you're definitely getting ahead of yourself if you think that whatever you're holding on to is a universal truth for all that is living. I've had that conversation countless times with people who've also gone through DMT breakthroughs: you're no less in a prison of your own mind when you think this way, you've only shifted your philosophical perspective into a place that anchors different beliefs in place. They appear entirely valid because you perceive less subjective suffering, but generalizing the idea that those beliefs are valid everywhere and for everyone is like believing that a singular value in a system of differential equations give the whole picture. There's a difference between solving your problems and solving everybody's problems, and thankfully the scientific work comes into place to bridge that gap (however slow the process might be).
I appreciate your intentions and I think there are nuggets of truth in what you write (re-integration helps you carry things further, meditation offers relief, a change of beliefs most often does lead to lasting results yes), however some people are allergic to blindly dogmatic thinking and I happen to be one of them. Your entire post could have been written to advocate for religion X, Y or Z btw, and people in each religion have just as valid of a claim as you do when it comes to their belief systems alleviating their suffering.
Mandating that one is bound to find the truth with a big T if one "does it right" is pretty much one of the things that as a guide for others through psychedelics I've never made the mistake of advocating for. Psychedelics are a journey, and like any journey you might come in with who you are and come out with different parts but the more you project rigid expectations the less you'll actually extract from the journey itself. Like any journey, two different people taking the same means of transportation and going to the same place, might extract two entirely different things.
It would do a lot of good to a subset of the psychonaut community to retain empathy and compassion when it comes to sharing about personal journeys.
