Wrong and inappropriate use has caused LSD to become my problem child.

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 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.

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.

In many instances, LSD actually produced terrifying and deleterious effects instead of beneficial effects, because of misuse, because it was a profanation.

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.
