Zhōuyì guàyáo jīngzhuàn xùnjiě 周易卦爻經傳訓解
Glosses on the Hexagram-and-Line Canon-and-Commentary of the Zhōuyì
by 蔡淵 Cài Yuān (撰) — zì Bójìng 伯靜, hào Jiézhāi 節齋, 1156–1236, of Jiànyáng 建陽, Fújiàn; eldest son of 蔡元定 Cài Yuándìng (Zhū Xī’s principal disciple), elder brother of 蔡沈 Cài Shěn (author of the Shàngshū jí zhuàn).
About the work
A two-juan canonical-and-commentary running gloss on the Shàng jīng and Xià jīng (the upper and lower canonical halves of the Yì), by Cài Yuān 蔡淵 — eldest son of 朱熹 Zhū Xī’s principal disciple 蔡元定 Cài Yuándìng (1135–1198) and head of the Cài-family scholarly dynasty in the second generation.
Bibliographic state: the present 2-juan Sìkù base-text is the surviving remnant of an originally 4-juan work. Zhū Yízūn’s Jīngyì kǎo records the Zhōuyì jīngzhuàn xùnjiě in 4 juan with the note “cún sān juan 存三卷” (“three juan extant”); Dǒng Zhēnqīng’s Zhōuyì huìtōng describes the original 4-juan structure in detail. The present 2-juan base, restricted to the canonical-text exposition of the upper-and-lower jīng alone, was titled Zhōuyì guàyáo jīngzhuàn xùnjiě by an unscrupulous book-dealer (shūjiǎ zuò wěi zhī jì 書賈作偽之技) who inserted “guàyáo” (hexagram-and-line) into the title to disguise the loss of the Xìcí / Wén yán / Shuō guà / Xù guà / Zá guà commentary that had filled the lost juan. The Sìkù editors deleted the inserted “guàyáo” and restored the original title for their record-keeping. The catalog meta retains the book-dealer-modified title for documentary fidelity to the surviving source.
The original structure, per Dǒng Zhēnqīng:
- Guàcí (hexagram-statement) at the head.
- Dà xiàng 大象 placed below the guàcí, indented one character.
- Tuàn zhuàn placed after the Dà xiàng, indented one character.
- Each yáocí (line-statement), then Xiǎo xiàng 小象 placed after, indented one character.
- Xìcí, Wén yán, Shuō guà, Xù guà, Zá guà — separately treated, all also indented one character.
The structural innovation: indentation as the typographic signal of canon-versus-commentary status. The guàcí and yáocí (the canonical text proper) are flush left; the Tuàn, Xiàng, Wén yán (the Confucian commentary, traditionally part of the Ten Wings) are indented. This is a typographic implementation of the ZhūXí gǔyì (ancient-Yì) recension principle: the wing-treatises are commentary, structurally distinct from but presentationally adjacent to the canon. The body of the present 2-juan base preserves this structure for the Dà xiàng / Tuàn / Xiǎo xiàng, confirming the authentic textual line.
Cài Shěn 蔡沈 (Cài Yuān’s brother) wrote a hòu xù 後序 (postface) for the work, preserved in Jīngyì kǎo. Cài Shěn’s postface specifically discusses the work’s exposition of Yì yǒu Tàijí 易有太極 (“the Yì contains the Great Ultimate” — Xìcí shàng 11), zhī zhì zhī zhōng 知至知終 (“knowing the arrival and the end” — Wén yán on Qián), and zhèng zhí yì fāng 正直義方 (“uprightness and rightness” — Wén yán on Kūn). All three are passages from the Xìcí / Wén yán, not from the upper-and-lower jīng. This conclusively confirms that the original work covered the Xìcí / Wén yán / Shuō guà etc., as Dǒng Zhēnqīng and Zhū Yízūn report.
The auto-preface (dated Kāixǐ yǐchǒu / 1205, tenth-month full-moon day, signed Jiànān — Cài Yuān’s local-name for Jiànyáng) gives the work’s program. The opening combines two Xìcí citations to form the methodological frame: Yì yǒu Tàijí 易有太極 (the Yì contains the Great Ultimate) + Yì wú sī yě, wú wèi yě, tōng hū zhòuyè zhī dào ér zhī 易无思也无為也通乎晝夜之道而知 (the Yì is without thought, without action, penetrates the way of day-and-night and knows). Combining these: “the [first quote] is the Yì*‘s root; the [second quote] in ‘Heaven and Earth setting their positions and the* Yì flowing within’ is the Yì*‘s use. In Heaven called* Yì*; in humans called nature; nature and the* Yì are not two principles. If a person can know the Yì*‘s root and also know its use, then he can follow his nature’s correctness and not a single affair will fall out of measure.*”
The pedagogical-method passage: the sage saw that “humans, after Heaven sent down their fundamental nature, immediately leaned upon form, and so failed to fully realize their nature”; therefore he made the yáng odd / yīn even drawings, set up imagery to display biàn (transformation), so that “the world, observing this, might exhaust the principle of nature-as-given and fully realize the nature-as-mandated.” Later sages added wording (Wén yán, Tuàn, Xiàng, Xìcí) as further glosses; the Yì-canon was thereby completed. But: “Books cannot exhaust words; words cannot exhaust intent. The Yì*‘s Way — how could it be exhausted by a book?*” The student must “observe imagery and savor wording, observe transformation and savor divination, must finally attain something of the wonder of without-thought-without-action — only then can the sage’s intent be seen.”
The auto-preface’s reference to the late father — “formerly the late master used to say: ‘the sage’s Way — only the Yì can fully exhaust it; the sage’s books — only the Yì is complete; what it values — wording, divination, image, transformation — all are means to comply with the principle of nature-and-mandate’” — invokes Cài Yuándìng (the father, d. 1198) and clearly places the work in the post-1198 grieving-and-completion phase of Cài Yuān’s lifework.
The composition window 1190–1205 reflects: Cài Yuándìng’s death in 1198 as the work’s pre-completion personal context (the auto-preface explicitly references the late father’s teachings); the auto-preface date 1205 as firm terminus. Cài Yuān’s Yì-studies under Zhū Xī (d. 1200) and his father provide the broader 1190s-onward composition arc.
Tiyao
We respectfully submit that Zhōuyì jīngzhuàn xùnjiě in two juan was composed by Cài Yuān of the Sòng. [Cài] Yuān, zì Bójìng, hào Jiézhāi, a man of Jiànyáng. We note: Zhū Yízūn’s Jīngyì kǎo — Cài Yuān’s Zhōuyì jīngzhuàn xùnjiě in four juan, with note “three juan extant.” This base-text has only the upper-and-lower jīng in two juan, titled Zhōuyì guàyáo jīngzhuàn xùnjiě — at variance with what [Zhū] Yízūn recorded.
According to Dǒng Zhēnqīng’s Zhōuyì huìtōng: this book places Dà xiàng below the guàcí, places Tuàn zhuàn after the Dà xiàng, places Xiǎo xiàng after each yáocí — all indented one character to distinguish from guà and yáo. The structural-arrangement matches this base-text — confirming this is not a forgery. Yet [Dǒng Zhēnqīng] also says the Xìcí, Wén yán, Shuō guà, Xù guà, Zá guà are also indented one character — but the present base-text has none of these.
Further, the Jīngyì kǎo preserves Cài Yuān’s brother Cài Shěn’s postface, saying: “the Yì yǒu Tàijí discussion, the zhī zhì zhī zhōng meaning, the zhèng zhí yì fāng expression — all are the great roots of meaning-and-principle, the highest essentials for later students; truly opening up what worthy predecessors had not opened up.” These passages are all in the Xìcí and Wén yán. So this book originally glossed the Xìcí, Wén yán, etc. — there is firm evidence; not merely a gloss of guà and yáo alone — there is no occasion to label-the-purpose with guàyáo. Evidently what [Dǒng] Zhēnqīng saw was the four-juan complete base-text; what [Zhū] Yízūn saw was missing one juan; this base-copy is missing yet another juan. The transmission-copyist concealed the residual gaps by adding the guàyáo two characters to the book-title — as if the original base only glossed the upper-and-lower jīng — this is a book-dealer’s forgery-craft, not to be relied on.
We now delete the guàyáo two characters and record the work under its original title, preserving its truth.
Respectfully revised and submitted, seventh month of the forty-fifth year of Qiánlóng [1780].

Abstract
Cài Yuān (蔡淵, 1156–1236), zì Bójìng 伯靜, hào Jiézhāi 節齋, of Jiànyáng 建陽 (Fújiàn). Eldest son of 蔡元定 Cài Yuándìng (1135–1198), Zhū Xī’s principal scholarly collaborator and the most important xiàngshù-and-numerology specialist of the Zhū-school inner circle; elder brother of 蔡沈 Cài Shěn (1167–1230), author of the canonical Shàngshū jí zhuàn 書集傳. The Cài family of Jiànyáng — Cài Fā 蔡發 → Cài Yuándìng → Cài Yuān / Cài Shěn / Cài Mò 蔡沕 / Cài Háng 蔡杭 — is the most important late-Sòng Dàoxué scholastic dynasty after the ZhūXī family proper.
Catalog-vs-external dating: the Kanripo catalog meta gives 1148–1236; CBDB id 10051 and the Sòngshǐ (juan 434, Rúlín zhuàn) give 1156–1236. The 1156–1236 dating is followed here per the project rule. (The catalog 1148 birth year would have made Cài Yuándìng a father at age 13 — biologically possible but unusual; the standard 1156 leaves Cài Yuándìng at 21 at his eldest son’s birth, which is normal.)
Methodologically Cài Yuān is a strict Zhū-school yìlǐ-with-disciplined-xiàngshù synthesizer. The work’s typographic-structural innovation — indentation to distinguish canon from commentary — implements the ZhūXí gǔyì recension principle in a directly readable form. The work was substantively the Cài-school’s textbook-of-record for Yì-pedagogy, used at the Cài-family Jiànyáng compound (the Lúmín shūyuàn 廬閩書院 and successor academies).
The auto-preface’s framing — Yì yǒu Tàijí + Yì wú sī wú wèi — combines the Xìcí’s metaphysical-grounding statement (the Yì contains the Great Ultimate) with the Xìcí’s mystical-receptivity statement (the Yì is without-thought-without-action). The combination is methodologically distinctive: it grounds the Yì in both a substantive metaphysical claim and a mystical-receptive practice. The student’s task is not only to understand the canonical doctrine but also to enter the without-thought-without-action condition through guān xiàng wán cí 觀象玩辭 (observing imagery and savoring wording).
The relationship to Zhū Xī’s Zhōuyì běnyì and to Cài Yuándìng’s Yì xué qǐméng 易學啟蒙 (the latter the joint ZhūCài work on the xiàngshù foundations): Cài Yuān’s Xùnjiě is the canonical-text-running-gloss complement to those programmatic-and-foundational works. The three together — Běnyì + Qǐméng + Xùnjiě — would have constituted the basic ZhūCài Yì curriculum.
The composition window 1190–1205 reflects Cài Yuān’s mature scholarship in the immediate post-Zhū-Xī (1200) and post-Cài-Yuándìng (1198) period. The Kāixǐ yǐchǒu (1205) auto-preface is the firm terminus.
The transmission state of the work has been gradually deteriorating: Dǒng Zhēnqīng (Yuán) saw the complete 4-juan; Zhū Yízūn (Qīng early) saw 3-juan; the Sìkù editors saw 2-juan with book-dealer-modified title. The pattern reflects the typical attrition of scholastic-line Yì-commentaries that are not picked up into the standardized canonical-curriculum (which the Zhū Běnyì was, but the Cài Xùnjiě was not).

Other points of interest
The typographic-indentation principle Cài Yuān adopts (canon flush left, commentary indented one character) is one of the cleanest Sòng-period typographic-and-philological innovations. It implements visually the gǔyì recension principle that Lǚ Zǔqiān (KR1a0043) and Zhū Xī had argued for at the textual level. Modern critical editions of the Yì (Zhōnghuá shūjú, Shànghǎi gǔjí, etc.) generally preserve this typographic distinction.
The Cài-family scholarly transmission — Cài Fā 蔡發 → Cài Yuándìng → Cài Yuān and Cài Shěn — is one of the most documented multi-generational scholastic-dynasty lines in Sòng intellectual history. The family compound at Jiànyáng was a major Dàoxué center after Zhū Xī’s death; the Càishì jiāpǔ 蔡氏家譜 preserves substantial documentary detail.
Cài Yuān’s companion work Yì xiàng yì yán 易象意言 (KR1a0053) handles the xiàng (imagery) dimension that the present Xùnjiě does not directly emphasize. Read together, the two works give a fuller picture of Cài Yuān’s Yì-program.
