Shadow

I watched a shadow move today. It is a tremendous meditative exercise, which helps define your place in the Universe. Sitting on a planet, rotating on its axis and orbiting a star. Find a shadow on a sunny day which you can see in relation to a background, such as a building, a rock, a tree. Focus on an edge of the shadow. Note its relation to a fixed object in its background, such a a window in a building, a leaf on the ground, etc.. Now simply relax, get comfortable and meditate on the shadow until you begin to perceive its motion. Of course, you must then experience the realization that you and the object are in motion, while the shadow is relatively fixed by its relation to the sun. Feel the earth rotating beneath you. It's a great ride.
