The productive sender is the outer world, the external reality including our own body. The receiver is our deep self, the conscious ego, which then transforms the outer stimuli into a psychological experience.

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".

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.

We can study material processes and various processes at the energetic level, that is what we can do as natural scientists. And then there comes something quite different, the psychic experience, which remains a mystery.

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

Psychedelic substances, if they are used in proper ways, are very helpful for mankind.

It is true that my discovery of LSD was a chance discovery, but it was the outcome of planned experiments and these experiments took place in the framework of systematic pharmaceutical, chemical research. It could better be described as serendipity. That means that you look for something, you have a certain plan, and then you find something else, different, that may nevertheless be useful.
