After some time, with my eyes closed, I began to enjoy this wonderful play of colors and forms, which it really was a pleasure to observe. Then I went to sleep and the next day I was fine. I felt quite fresh, like a newborn.

It is true that my discovery of LSD was a chance discovery, but it was the outcome of planned experiments and these experiments took place in the framework of systematic pharmaceutical, chemical research. It could better be described as serendipity.

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.

When you study natural science and the miracles of creation, if you don't turn into a mystic you are not a natural scientist.

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

I believe that if people would learn to use LSD's vision-inducing capability more wisely, under suitable conditions, in medical practice and in conjunction with meditation, then in the future this problem child could become a wonderchild.

This possibility to change reality, which exists in everyone, represents the real freedom of every human individual. He has an enormous possibility to change his world view.
