As I sit in the early morning darkness, I watch a Star rise. I know it is rising, because there is a leafless branch between me and the Star that I can use as a reference. When I first sit down, it is below the branch, then behind, then above. Sky starts to shine brighter, and I know that the Sun is not for behind.
All this broadens my perspective to include the slowly turning Earth that brings me morning, the path of Earth around Sun that brings Winter, and the place in which our solar system lives in the Milky-way. It's easy for me to lose track of this larger perspective, and I am grateful to Star for reminding me.
Today, I will be remembering Star as I walk through my day, and thinking about how walking on Earth is like walking on an enormous log floating in the river of Space.
