I think that the possibility to have psychedelic experience is inborn. These psychedelics - very similar compounds are in our brain; of all the compounds which you find in the plant kingdom only the psychedelics are so closely related chemically to these brain factors, which we already have. We speak about the paradise of childhood. When I had this vision and beautiful experience as a child, this is no wonder, because we have these compounds already in our brain. -Albert Hoffman
