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.

In a dreamlike state, with eyes closed (I found the daylight too unpleasantly glaring), I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors.

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

Through my LSD experience and my new picture of reality, I became aware of the wonder of creation, the magnificence of nature and of the animal and plant kingdom. I became very sensitive to what will happen to all this and all of us.

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.

Evolution of mankind is paralleled by the increase and expansion of consciousness.
