I unroll my thick green yoga mat in the small flat space beside the shallow end of the pool. It’s full dark already, but I am determined to do my yoga. I face west to do my sun salutes and picture the sun still setting somewhere beyond the curve of the world. After, lying on my back in chavasana, there are more stars in the sky than I remember seeing here before. The moon hangs above me, just to the left. I lie still for a long time, open to the sky, bathing in the silent, magic light.
