I once heard the pianist, Arthur Rubinstein, being interviewed. At one point he was asked to share his experience of playing Chopin's Nocturnes. He said in effect, "I do not know what it is. But over and over again I have had the experience of sitting in a crowded concert hall playing the Nocturnes and I can feel everyone in the room waiting for the next note." In this moment of waiting, all present find their contemplative community in their oneness with one another in the boundless mystery that enraptures them.
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.
