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

What one commonly takes as 'the reality,' including the reality of one's own individual person, by no means signifies something fixed, but rather something that is ambiguous - that there is not only one, but that there are many realities, each comprising also a different consciousness of the ego.

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

The truth will finally come out and the truth is: If LSD is used in the right way, it is a very important and very useful agent.

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.

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.
