What is revealed through the psychedelic experience, I think, is a higher dimensional perspective on reality. And I use 'higher dimensional' in the mathematical sense.
The testimony of DMT, for me, is that there is a nearby dimension, teeming with intelligences, that from one of the more conservative perspectives seems like an ecology of souls.
And science, when it examines psychedelics, as it will and must, is going to discover a revolution, I believe, that will put all the previous revolutions in perspective.
