Balance of Change

From the Thoth Tarot, the Two of Disks; from the Vertical Oracle, Unsupervised:

          Light becomes dark and expended energy is followed by rest. Nothing can sustain itself without balance that comes from change. I'm running on two hours of sleep, which means a nap will be in order sooner rather than later. My 'unsupervised' time will be under the covers, with no one to bother me (except maybe a cat napping beside me). ZZzzzzzz
