Hi Geoffrey,
Welcome to the Nexus. Great to have you here. I'm not sure how we compare to a motorcycle forum, but I do hope you will enjoy your time here.
Some potential good starting reading resources might be, "DMT: The Spirit Molecule," by Strassman, and PIHKAL & TIHKAL by the Shulgins.
When it comes to DMT, it's going to be difficult for you to prove a link between it and anything metaphysical, but I do know there is many a psychonaut who feels there must be something. And I applaud your desire to learn as much as possible. Hard to go wrong there.
Have you had an opportunity to try DMT yet? How about other psychedelics? Anything you can tell us about your experience level, impressions, etc. . .
Again, a warm welcome to you.
"But even if nothing lasts and everything is lost, there is still the intrinsic value of the moment. The present moment, ultimately, is more than enough, a gift of grace and unfathomable value, which our friend and lover death paints in stark relief."-Rick Doblin, Ph.D. MAPS President, MAPS Bulletin Vol. XX, No. 1, pg. 2Hyperspace LOVES YOU
