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.

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.

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.

We need a new concept of reality and a new set of values for things to change in a positive direction. LSD could help to generate such a new concept.

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.

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.

LSD was my "wonder child", we had a positive reaction from everywhere in the world. Around two thousand publications about it appeared in scientific journals and everything was fine. Then, at the beginning of the 1960s, here in the United States, LSD became a drug of abuse. In a short time, this wave of popular use swept the country and it became "drug number one". It was then used without caution and people were not prepared and informed about its deep effects. Instead of a "wonder child", LSD suddenly became my "problem child".
