Hi Rohan,
Welcome to the Nexus. I'll be a pedant and say I would hope you find no "guides" here but do find the information and knowledge base that you seek. Please be sure to take a good look around - there are a lot of very rich subforums and the wiki is amazing (upper right hand corner for wiki link). From Health & Safety, to great extraction teks to "Hyperspace Lexicon," it's all there.
If you might be willing to inform us a little bit more about yourself I know it would be appreciated. Your life's important pursuits. Your ideas. Your history with psychedelics. When you tried DMT did you do it via vaporization or take an oral brew? Things of this nature might help us to get to know you a bit more.
Please do not hesitate to post any questions as they come up. Great to see you here.
"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
