It's very, very dangerous to lose contact with living nature.

LSD is really just a small chemical modification of a very old sacred drug of Mexico. LSD belongs, therefore, by its chemical structure and by its activity, in the group of the magic plants of Mesoamerica. It does not occur in nature as such, but it represents just a small chemical variation of natural material.

In many instances, LSD actually produced terrifying and deleterious effects instead of beneficial effects, because of misuse, because it was a profanation.

We can study material processes and various processes at the energetic level, that is what we can do as natural scientists. And then there comes something quite different, the psychic experience, which remains a mystery.

Psychedelic substances, if they are used in proper ways, are very helpful for mankind.

I became very sensitive to what will happen to all this and all of us.

LSD wanted to tell me something. It gave me an inner joy, an open mindedness, a gratefulness, open eyes and an internal sensitivity for the miracles of creation.
