Simply put, when you look out at the physical Universe, you look into one level of Universal Mind Consciousness or the Mind of God. And, through the physical instruments of today's science, the further out into the farthest reaches of the Universe you look, the deeper into your own consciousness you can enter.
The Biblical words, "as above, so below," can be taken quite literally. It is a mystical reality that speaks the eternal truth that all life is One and the Same, and that ultimately there is but One Life everywhere present-be it in the vastness of what appears as outer space or in the more finite existence of a human. From the appearance of the tremendous mass of a star to the appearance of a pebble or a droplet of water, each comes from One Universal Life Consciousness manifesting as us all.
Eventually, whether in this physical lifetime or another, we become aware of the various states of our beingness; and through the Grace of God's Presence, we integrate all levels into a harmonious working Wholeness of Beingness.
