One very often overlooked characteristic of light passing through and around something is that it almost always creates a shadow in its wake. As we grow and evolve as human beings, we pass through experiences in life that help us grow and expand our light. Our consciousness. The thing is at the same time as we grow in our own personal light, we also grow in our own personal shadow. The light and the shadow represent two sides of the same coin. The coin of our true whole self.
