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.

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".

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

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.

LSD should be treated as a sacred drug and receive corresponding preparation, preparation of quite a different kind than other psychotropic agents. It is one kind of thing if you have a pain-relieving substance or some euphoriant and (another to) have an agent that engages the very essence of human beings, their consciousness.

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.

LSD is just a tool to turn us into what we are supposed to be.
