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.

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?

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.

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

Reality became for me a problem after my experience with LSD. Before, I had believed there was only one reality, the reality of everyday life. Just one true reality and the rest was imagination and was not real. But under the influence of LSD, I entered into realities which were as real and even more real than the one of everyday. And I thought about the nature of reality and I got some deeper insights.

I was completely astonished by the beauty of nature. Our eyes see just a small fraction of the light in the world. It is a trick to make a colored world, which does not exist outside of human beings.

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