This is a general comment that you should take a committed dose of whatever it is you're taking so that there is no ambiguity, because there's nothing worse than a sub-threshold psychedelic experience.
Terence McKennaAt still higher doses psilocybin triggers this activity in the language-forming capacity of the brain that manifests as song and vision. Psilocybin may have synergized the emergence of higher forms of psychic organization out of primitive protohuman animals. It can be seen as a kind of evolutionary enzyme, or evolutionary catalyst.

Terence McKennaI see the psychedelic experience as a birthright, and we can't have a free society until people are free to explore their own mind.
Terence McKennaI often like to think that our map of the world is wrong, that where we have centered physics, we should actually place literature as the central metaphor that we want to work out from. Because I think literature occupies the same relationship to life that life occupies to death. A book is life with one dimension pulled out of it. And life is something that lacks a dimension which death will give it. I imagine death to be a kind of release into the imagination in the sense that for characters in a book, what we experience is an unimaginable dimension of freedom.
