DIVISION 16 (第十六)

Reach the pole of emptiness.
Maintain tranquility in the center:
The myriad creatures all rise together,
And by this, I see their return.
Things (come forth) in great numbers;
Each one returns to its root.

Returning to the root is called tranquility.
Tranquility is called the inevitable unfolding of things.
Returning to the inevitable unfolding of things is called cháng,
And to understand cháng is called Enlightenment.
To not know cháng is to be reckless and wild.
If you are reckless and wild, your actions will lead to misfortune.
To know cháng, one becomes all-embracing.
To be all-embracing is to be impartial.
To be impartial is to be kingly.
To be kingly is to be (like) Heaven.
To be (like) Heaven is to be (one with) the Dào.
If you are one with the Dào, to the end of your days you will suffer no harm.

COMMENTARY by Koeng S. Wan:
Enlightenment is to know the nature of all things, which when attained enables one to abide by the Dào, achieve tranquility, satisfy physical needs (Division 32), live long (Division 33), and make peaceable society possible (Division 39). One can achieve enlightenment through quiet contemplation by "reaching the pole of emptiness" whereby one can become one with the Dào (Divisions 14 and 15) by gaining an understanding of cháng (常), the "returning to the inevitable unfolding of things".

Enlightenment is the understanding of cháng, the "returning to the inevitable unfolding of things", which is the understanding of the nature of the existence of all things (e.g. being all-embracing) -- essentially the understanding of how all things change: i.e., how things emerge from their roots (living things being born); how things relate to other things; how things transform throughout their existence; and how they return to their root (living things dying). Importantly, understanding of cháng is not limited only to things in nature but to every thing in existence, including people. Division 49 of the Lǎo Zǐ says:

The shèng rén's (sage's) mind is not his own.
He takes as his own the mind of the people.

Cháng is understood by one reaching a state of mind called the "pole of emptiness" which is an emulation of the emptiness that characterizes the Dào as an abyss that is the origin of all creation (Division 4 and 25). This mental emptiness is useful (Division 11) as it allows one to come to know how creation emerged from the Dào (Division 42), including the birth of Heaven and Earth, and the emergence of all things. To grow and develop closely to one's roots leads one to be firmly rooted (Division 54), which is the fulfillment of one's own nature, i.e. abiding by the Dào. Consequently, to not understand cháng is recklessness because it places things, including oneself (Division 33), into an imbalanced contention with other things (Divisions 29, 34, and 39).

Life and death are linked as things "unfold" from their physical as well as their emotive or spiritual natures (Division 39) which are their roots. For example, the Xuán Pìn Gate is the root of Heaven and Earth (Division 6); heavy is the root of the light (Division 26); and the humble is root of the exalted (Division 39). The unfolding, however, is neither deterministic or fatalistic, as Division 51 explains that while the Dào and rears and nurtures life, respectively, "Matter shapes them and conditions complete them."

Finally, when one becomes all-embracing, one becomes impartial which emulates Heaven and Earth (Division 5), including their long lives (Division 7).

DIVISION 4 (第四)

The Dào is empty,
Use it; it never needs filling.
Like an abyss! It seems to be ancestor to the ten thousand things.
It blunts the sharp,
Unties the tangles,
Softens the glare,
And settles the dust.
Submerged! It seems perhaps to exist.
I do not know whose son it is.
It is an image of what precedes God.

COMMENTARY by Koeng S. Wan:
The Dào is an ancient, limitless void that is the ancestor of all creation. Though it is empty but somehow like water, the Dào can be used to help bring peaceful relations between people and bring peace of mind.

The sharp, tangled, glared, and dusty are all extreme states, and the Dào moderates them by dulling, untying, softening, and settling them, respectively. As both abyss (yuān 淵) and submerged (zhàn 湛) have etymologies related to water^[1], the Lǎo Zǐ compares the effects of the Dào to the effects of water. (Division 8 says water is close to the Dào, and Division 34 compares the Dào to a flood.) Sharpened metal implements become dull as they oxidize and react with other compounds in water. A tangled or knotted cord loosens when it shrinks after water expands it or as water facilitates rotting. Clouds and fog block light. Rain removes the dust from the air.

The physical transformational effects of water are metaphors for the transformational effects of the Dào on people. As opposed to glare and dust which occur naturally, the sharpened and the knotted result from the efforts of people, though we can have glare from one's attire (see Division 3).

As for sharp, the Lǎo Zǐ uses it to describe the violent capacity of weapons (see Divisions 36 and 53). The dulling effect of the Dào on weapons is peace. So the dào is to blunt the sharp (see Division 56), a general call for pacifism.

As for tangles, contention among people is brought about by entangled human relationships rooted in ambitions and desires (Division 3). Contention is reduced when the roots of conflict, personal ambitions and desires, are extinguished (see Divisions 19 and 57). So the dào is to loosen tangles (see Division 56).

As for glare, people can flaunt “alluring things” to cause others to be confused (Division 3). The softening effect of the Dào is modest attire, that will reduce confusion. So the dào is to soften the glare (Division 56).

See Division 42 on the Dào's role in being the ancestor of all things.
