Rhythm is the basis of life, not steady forward progress. The forces of creation, destruction, and preservation have a whirling, dynamic interaction.
Every phase of evolution commences by being in a state of unstable force and proceeds through organization to equilibrium. Equilibrium having been achieved, no further development is possible without once more oversetting the A journey of a thousand miles starts in front of your feet. Whosoever acts spoils it. Whosoever keeps loses it.
Force never moves in a straight line, but always in a curve vast as the universe, and therefore eventually returns whence it issued forth, but upon a higher arc, for the universe has progressed since it started.
The pure impulse of dynamic creation is formless; and being formless, the creation it gives rise to can assume any and every form.
