And Thereby The World Is Formed

Duration is a state whose movement is not worn down by hindrances. It is not a state of rest, for mere standstill is regression. Duration is rather the self-contained and therefore self-renewing movementof an organized, firmly integrated whole, taking place in accordance with immutable laws and beginning anew at every ending. The end is reached by an inward movement, by inhalation, systole, contraction, and this movement turns into a new beginning, in which the movement is directed outward, in exhalation, diastole, expansion.
Heavenly bodies exemplify duration. they move in their fixed orbits, and because of this their light-giving power endures. The seasons of the year follow a fixed law of change and transformation, hence can produce effects that endure.
So likewise the dedicated man embodies an enduring meaning in his way of life, and thereby the world is formed. In that which gives things their duration, we come to understand the nature of all beings in heaven and on earth.
