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".

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.

The characteristic property of hallucinogens, to suspend the boundaries between the experiencing self and the outer world in an ecstatic, emotional experience, makes it posible with their help, and after suitable internal and external perparation, to evoke a mystical experience according to plan, so to speak. I see the true importance of LSD in the possibility of providing material aid to meditation aimed at the mystical experience of a deeper, comprehensive reality. Such a use accords entirely with the essence and working character of LSD as a sacred drug.

We can study various psychic functions and also the more primitive sensory functions, such as seeing, hearing, and so on, which constitute our image of our everyday world. They have a material side and the psychic side. And that is a gap which you cannot explain.

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

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.

Consciousness is Gods' gift to mankind.
