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...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.
-- Dr. Albert Hoffman, the discoverer of LSD
