Much of our work is invisible and intangible. You cannot measure it by human means; and sometimes a period of silent reflection will accomplish more good than if the time had been spent in outward activity. Our work is immaterial where we are and what we do; the thing that matters is who we are and what we intend. Constant preoccupation with exterior work handicaps our knowledge of ourselves and of our intentions.
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.
