至虛，極也；守情（静），表也。
萬物旁作，吾以觀其復也。
天物雲雲，各復歸於其根，曰静。
静，是胃復命。復命，常也；
知常，明也；不知常，妄妄作凶；
知常容，容乃公，公乃王，王乃天，天乃道，
道乃久，沕身不怠。

Pursue in your spiritual world to the extreme. Let your heart be at peace.
All creatures living out there. I watch their life cycles.
Each separate being in the universe, returns to its source.
Returning to the source is serenity/calmness.
If you don’t realize your source/gift/mission, you tumble in confusion and sorrow.
When you realize the source, you naturally become wise/enlightened, tolerant, equal, dignified as a king, broad as celestial, forever as Dao. Even when your body is immersed in the water (death), your spirit won’t die.

Chapter 16 is about Wu-Wei in action.

What is Wu (无)? It is your talent, nature, mission.

What is Wu-Wei (无为)? It is the inherent mind, the natural mind. The essential part that is the core of yourself.

Chapter 16 relates to the Yi Jing hexagram 24, ䷗, 复 (fù), which means "returning."
