“I believe that shortly after LSD was discovered, it was recognized as being of great value to psychoanalysis and psychiatry. It was not considered to be an escape. It was a very important discovery at that time, and for fifteen years it could be used legally in psychiatric treatment and for scientific study in humans. During this time, Delysid, the name I gave to LSD, was used safely, and was the subject of thousands of publications in the professional literature. Actually, just last week, I had visitors from the Albert Hofmann Foundation, to whom I gave all of the original documentation, which had been stored at the Sandoz Laboratories. This early work was very well documented, and shows how well research with LSD went until it became part of the drug scene in the 1960s. So, from originally being part of the therapeutic pharmacopeia, LSD became a drug of the street and inevitably it was made illegal. Because of this reputation, it became unavailable to the medical field, and so the research, which had been very open, was stopped. Now it appears that this research may start again. The importance of such investigations appears to be recognized by the health authorities, and so it is my hope that finally the prohibition is coming to an end, and the medical field can return to the explorations which were forced to stop thirty years ago.”

Context: The characteristic property of hallucinogens, to suspend the boundaries between the experiencing self and the outer world in an ecstatic, emotional experience, makes it possible with their help, and after suitable internal and external preparation, as it was accomplished in a perfect way at Eleusis, to evoke a mystical experience according to plan, so to speak.
Meditation is a preparation for the same goal that was aspired to and was attained in the Eleusinian Mysteries. Accordingly it seems feasible that in the future, with the help of LSD, the mystical vision, crowning meditation, could be made accessible to an increasing number of practitioners of meditation
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.
