God is creatively present in everyone in every moment whether we are aware of it or not. But when we are in the state of silent gratefulness, we are aware of God's Presence.
~ from THE ETERNAL NOW by Paul Tillich
The tree of life is one's inner axis that grows from the depths of the earth and reaches to the heavens. It connects together the primal opposites of the temporal and the eternal. It is life lived from the "still center of the turning world" and it embraces the deepest human mystery: that we are eternal beings living in a world of time.
