"I have always had this very strong, call it a feeling, call it a prejudice, call it a conviction ... that the mysteries are not easily available. You have to earn entrance into them. You didn't learn things for too little. You had to pay a price. And I felt that LSD was just blasting superhighways into the mysteries. And what I really didn't like about LSD is that people who were taking it were seeming to become less and less as they took it. They got emptier and more vapid."
