“This is an old trick which has existed from time immemorial—chewing a piece of leaf or experimenting with the latest chemical to bring about a temporary alteration in the structure of the brain cells, a greater sensitivity and heightened perception which give a semblance of reality. This demand for more and more experiences shows the inward poverty of man. We think that through experiences we can escape from ourselves but these experiences are conditioned by what we are. If the mind is petty, jealous, anxious, it may take the very latest form of drug but it will still see only its own little creation, its own little projections from its own conditioned background.”
