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.

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 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.

When you study natural science and the miracles of creation, if you don't turn into a mystic you are not a natural scientist.

People who use LSD today know how to use it. Therefore, I hope that the health authorities will get the insight that LSD, if it is used properly, is not a dangerous drug. We actually should not refer to it as drug; this word has a very bad connotation. We should use another name.

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.
