Tao Te Ching Chapter 15: The Ancient Masters — Meaning and Reading

Tao Te Ching chapter 15 describes the ancient masters of the Tao through seven similes: cautious as if crossing a winter river, wary of neighbors, grave as a guest, yielding like melting ice, simple as uncarved wood, open as a valley, murky as muddy water. It turns on the core question: who can let muddy water clear through stillness, and let stillness gradually come alive?

Key takeaways

1. The ancient masters: Chapter 15 portrays the masters of the Tao with similes of caution — crossing a winter stream, hesitating like a traveler.
2. The muddy-water question: 孰能浊以静之徐清 — who can let the muddy settle through stillness?
3. Caution with vitality: Stillness slowly gives way to clarity.
4. Not literal biography: The imagery is deliberately elusive — an image of the sage.

The chapter in context

The received text of chapter 15 opens with a portrait of the ancient masters: 古之善为士者，微妙玄通，深不可识 ("the ancient masters were subtle, mysterious, penetrating, and deep beyond fathoming"). Because they cannot be fathomed, the text says, it can only force a description of their appearance (夫唯不可识，故强为之容). That framing matters: the imagery that follows is an approximate sketch, not a report about identifiable people.

The sketch consists of seven similes: crossing a winter stream (豫兮若冬涉川), wary of neighbors (犹兮若畏四邻), grave as a guest (俨兮其若客), melting ice (涣兮其若凌释), uncarved wood (敦兮其若朴), a valley (旷兮其若谷), and muddy water (混兮其若浊). The chapter then turns to the closing pair of questions — 孰能浊以静之徐清？孰能安以久动之徐生？ — and ends on not desiring fullness: 保此道者，不欲盈 (those who preserve this Tao do not desire fullness).

Chapter 15 is attested in the oldest stratum of the text: material matching it appears in the Guodian bamboo slips (a tomb dated c. 300 BCE), the earliest extant Laozi material. In the Oriens deck, the chapter's card sits with chapter 16 under the theme "Stillness" — the muddy water that settles by stillness looks ahead to chapter 16's instruction.

The masters' images: hesitation, mud, and clarity

The full received text (simplified Chinese; composite reading — see the edition note below):

古之善为士者，微妙玄通，深不可识。夫唯不可识，故强为之容；豫兮若冬涉川；犹兮若畏四邻；俨兮其若客；涣兮其若凌释；敦兮其若朴；旷兮其若谷；混兮其若浊；澹兮其若海；飂兮若无止。孰能浊以静之徐清？孰能安以久动之徐生？保此道者，不欲盈。夫唯不盈，故能蔽而新成。

Two further lines, 澹兮其若海；飂兮若无止, appear in some editions and are not part of the core seven.

Pinyin:

Composite reading (no single edition prints this exact text): the simile lines follow a received-text edition that includes 澹兮其若海；飂兮若无止 (present in some editions, absent in others — e.g., the Wang Bi line); the second question follows the Oriens card's reading with 久, where other received editions print 孰能安以动之徐生 without 久.

Translation approach 1 — the Oriens card rendering. The deck card for this chapter (tao-015-ancient-masters) translates the closing questions as: "Who can make muddy water clear by letting it be still? Who can make stillness come alive through gentle, gradual movement?" This follows the syntax closely: 孰能 (who can), 以静 (by means of stillness), 徐 (gradually). The "gentle, gradual movement" of the second question turns stillness into something that can itself come alive. The card quotes only the closing pair — a partial quote, not the whole chapter.

Legge's rendering (1891). Legge renders the same passage as: "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." Legge splits each question into an instruction, making the chapter read like a recipe for settling rather than a riddle — a real interpretive difference between translators.

Edition notes. Received editions differ on several points. The second question appears as 孰能安以久动之徐生 (with 久, "after a long time") in the Oriens card, and as 孰能安以动之徐生 without it in other received-text editions. Two simile lines — 澹兮其若海；飂兮若无止 ("vast as the sea; drifting as if never stopping") — appear in some editions and are absent from others. The melting-ice simile is printed variously as 涣兮其若凌释 or 涣兮若冰之將釋, and the closing line is printed 蔽而新成 ("worn out yet renewed") in some editions and 蔽不新成 in others. These are genuine variants across the tradition, not errors; no single printed version is "the" text.

What this does not mean

The masters are not passive hermits. Every simile describes watchfulness, courtesy, and responsiveness — crossing a winter stream is dangerous precisely because it requires attention; a guest is alert to the situation around them. The chapter does not promise calm as a reward, and the muddy-water image is not a self-help guarantee that resting will produce clarity.

The imagery is deliberately elusive — the text says the masters are too deep to be fathomed, so it can only sketch their appearance. The similes are not a hidden code to decode literally, and they are not literal biography of real individuals. Likewise, the closing line on not desiring fullness (不欲盈) is not a demand for performed humility; in Legge's rendering the masters are not full of themselves, so they "can afford to seem worn and not appear new and complete."

No translation of the similes is "the correct" one; the variants are part of the text's history.

FAQ

Who are the ancient masters in Tao Te Ching chapter 15?

The chapter does not name individuals. It opens with a portrait of 古之善为士者 — the ancients skilled in the way of the officer/master — who are "subtle, mysterious, penetrating, and deep beyond fathoming." Because they cannot be fathomed, the text offers only a forced sketch of how they appear.

What does the muddy water verse mean?

孰能浊以静之徐清？ asks who can make muddy water clear through stillness, gradually. The image is the chapter's core: clarity comes not from stirring or forcing, but from letting the sediment settle — paired with the second question, who can make settled stillness come alive again through gentle, gradual movement.

Why is chapter 15 full of similes?

Because the masters are described as 深不可识 — too deep to be fathomed — the text says it can only describe their appearance (强为之容), so it reaches for similes rather than definitions: winter river, wary guest, melting ice, uncarved wood, valley, muddy water. The imagery is deliberately elusive, not a code to decode literally.

What does stillness do in chapter 15?

Stillness is what lets muddy water clear; the second question then shows stillness holding life within it — it can be stirred into gradual motion again. The portrait pairs caution with vitality: clarity from not forcing.

Why do different editions of the chapter differ?

The tradition is genuinely varied. The second question appears with and without 久 ("after a long time"); the lines 澹兮其若海；飂兮若无止 are present in some editions and absent from others; and the closing line is printed 蔽而新成 in some editions and 蔽不新成 in others. None of these is an error, and none is the single "correct" reading.
