> I don't want to be a druggie
Of course! I don't think anyone really does, and like I said, with psychedelics this is easier than usual because they are physically anti-addictive, partly due to their tolerance period. That being said, some can get "lost in the sauce" so to speak, so if you end up taking on psys, be careful, and do your research.
>Which ones are the best for self-improvement
The ones that have the best reputations for drastic personal improvement are LSD, Psilocybin mushrooms, DMT and Ayahuyasca, imho. They have the best track records and seem the most "navigable" compared to some of the lesser known ones.
>what have they done for you?
Well, to try and sum up my "inner journeying", since taking psychedelics I have learned to respect and love the world as a whole, accept things I cannot change, change the things I can, and just kinda see the world with a more appreciative eye. That's the cumulative effects, though, after years and after much experience integration. Actually taking them is another story entirely, which can be beautiful, chaotic, terrifying, wonderous, full of glory, everything wrapped up in one. Sometimes you feel psychotic, like you've gone crazy and will never recover or get back to feeling how it was before, but this usually passes after a few hours to days and you'll be back in your old world with a fresh perspective in life.
Psychedelics are boundary dissolving, creatively catalystic, substances that engage, strengthen, and multiply the amount of connections happening in your brain. You're able to see the world in new ways you never have before, which is great for people stuck in rigid thought structures or those who have mental troubles (YES! psychedleics such as mushrooms are even being used byu clinicians these days to treat stuff like PTSD and depression).
>Also which are the best to meditate on.
I need to practice with this more, but I tried meditating on LSD a few times ago with some interesting results
