Thanks man ^_^ I'm not all that familiar with Timothy Leary to be honest but I'm quite chuffed to know we made a similar observation. Aldous Huxley makes a great analogy in The Doors of Perception aswell, he likens our minds filter on information to a tap that with the use of psychedelics can be adjusted to allow more information in. I think in that analogy DMT would have to be equivilent to just smashing the whole tap of the pipe though to be honest

I definately agree that entheogens are the next step for humanity if we really want to evolve further, if only science could get past this research taboo it's still clinging on to I think it could have alot of it's questions answered and theoretical gaps filled.
