"[...] I let no physical activity creep into that beautiful picture. No paddling the canoe or anything like that. I am just comfortably floating and very, very relaxed. If that doesn't stop the urgent thought flow, there are alternate antidotes. Try visualizing yourself on a black velvet hammock and everywhere you look it shows black.[...] The last resort trick I use to block out problem thinking is to close my eyes and imagine I am looking at a blank television screen. Then I ask myself, "What do you see? What do you see?" Soon things appear on the screen and I describe them to myself. Amazing scenes produced by my subconscious mind blot out worrisome cares of the real world and soon I am asleep."
