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.
Terence McKennaPsychedelic drugs, especially psilocybin, allow a searchlight to be thrown on these deeper levels of the psyche, as Jung correctly stated. But it is not a museum of archetypes or psychic constructs, as he seemed to assume. It is a frontier of wholeness into which any person, so motivated and so courageous as to wish to do it, can go and leave the mundane plane far behind.
