"...Tibetan prayer wheels: you write a prayer on a paper, put the rolled paper on a wheel, and turn it automatically, without thinking. In this way, the wheel itself is praying for me, instead of me - or more precisely, I myself am praying through the medium of the wheel. The beauty of it all is that in my psychological inferiority I can think about whatever I want, I can yield to the most dirty and obscene fantasies, and it does not matter because - to use a good old Stalinist expression - 'whatever I am thinking, objectively I am praying.'"
