So sometimes things are ahead and sometimes they are behind; Sometimes breathing is hard, sometimes it comes easily; Sometimes there is strength and sometimes weakness; Sometimes one is up and sometimes down. Therefore the sage avoids extremes, excesses, and complacency.

Muddy water, let stand, becomes clear.

Heaven's Way gives no favors. It always remains with good people.

If Heaven were not clear it might rend. If Earth were not firm it might crumble.

Happiness perches on misery. Misery crouches beneath happiness.

Movement overcomes cold.

To manage your mind, know that there is nothing, and then relinquish all attachment to nothingness.
