I am going to assume you have watched "The Spirit Molecule"? If not, do that. And when you do, take some of the theories with a grain of salt, but it's an awesome documentary either way.
And it goes without saying, I could listen to Terrence McKenna talk about nearly anything for hours on end. If all else fails, listen to McKenna.
"'Tis true, without falsehood, certain and most true.
That which is below is as that which is above, and that which is above is as that which is below, to accomplish the miracle of the One thing.
And as all things have arisen from one by the meditation of one: so all things have their birth from this one thing by adaptation.
The Sun is its father, the Moon its mother,
the wind hath carried it in its belly, the earth its nurse."
-Hermes Mercurius Trismegistus
