ing. This is called the Form of the Formless,
and the Semblance of the Invisible; this is called the Fleeting and
Indeterminable.

3. We meet it and do not see its Front; we follow it, and do not see
its Back. When we can lay hold of the Tao of old to direct the things
of the present day, and are able to know it as it was of old in the
beginning, this is called (unwinding) the clue of Tao.

15. 1. The skilful masters (of the Tao) in old times, with a subtle
and exquisite penetration, comprehended its mysteries, and were deep
(also) so as to elude men's knowledge. As they were thus beyond men's
knowledge, I will make an effort to describe of what sort they
appeared to be.

2. Shrinking looked they like those who wade through a stream in
winter; irresolute like those who are afraid of all around them; grave
like a guest (in awe of his host); evanescent like ice that is melting
away; unpretentious like wood that has not been fashioned into
anything; vacant like a valley, and dull like muddy water.

3. Who can (make) the muddy water (clear)? Let it be still, and it
will gradually become clear. Who can secure the condition of rest?
Let movement go on, and the condition of rest will gradually arise.

4. They who preserve this method of the Tao do not wish to be full (of
themselves). It is through their not being full of themselves that
they can afford to seem worn and not appear new and complete.

16. 1. The (state of) vacancy should be brought to the utmost degree,
and that of stillness guarded with unwearying vigour. All things
alike go through their processes of activity, and (then) we see them
return (to their original state). When things (in the vegetable
world) have displayed their luxuriant growth, we see each of them
return to its root. This returning to their root is what we call the
state of stillness; and that stillness may be called a reporting that
they have fulfilled their appointed end.

2. The report of that fulfilment is the regular, unchanging rule. To
know that unchanging rule is to be intelligent; not to know it leads
to wild movements and evil issues. The knowledge of that unchanging
rule produces a (grand) capacity and forbearance, and that capacity
and forbearance lead to a community (of feeling with all things).
From this community of feeling comes a kingliness of character; and he
who is king-like goes on to be heaven-like. In that likeness to
heaven he possesses the Tao. Poss
