People in exile are experts on roots and energy. They know how much energy is needed to extract roots, how much energy is needed to stay uprooted, and, because a state of uprootedness is unsustainable over the long run, how much to sink roots deep into the ground again. I remember standing in North Dakota and looking toward the horizon. One can actually see Earth as a globe - the slight curve of the horizon, where the winds come from that bend the grass and the few trees, and where the clouds gather that sweep overhead, only to disappear again and make way for the blue sky. Sometimes, looking toward the horizon, I would feel an overwhelming joy, seeing mountains in the distance. It was usually a short emotion, as I realized that my mind had played tricks. Those were not mountains, could not be mountains. They were clouds that had swept me away toward home, mirroring a more familiar landscape.
