We have created a world that is bittersweet. Things are amusing but, at the same time, not so amusing. Sometimes things seem terribly funny but, on the other hand, terribly sad. Life has the quality of a game that has trapped us. The setup of mind has created the whole thing—the realm of duality, which is ego. In meditation we work on this creator of duality rather than on the creation. That is beginning at the beginning.
