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.

People who use LSD today know how to use it. Therefore, I hope that the health authorities will get the insight that LSD, if it is used properly, is not a dangerous drug. We actually should not refer to it as drug; this word has a very bad connotation. We should use another name.

Wrong and inappropriate use has caused LSD to become my problem child.

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

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

I suddenly became strangely inebriated. The external world became changed as in a dream. Objects appeared to gain in relief; they assumed unusual dimensions; and colors became more glowing. Even self-perception and the sense of time were changed. When the eyes were closed, colored pictures flashed past in a quickly changing kaleidoscope. After a few hours, the not unpleasant inebriation, which had been experienced whilst I was fully conscious, disappeared. What had caused this condition?

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