A Clap of Spring Thunder: The Awakening of Life and the Way of Dormancy in the Jingzhe Solar Term
This article offers a deep reading of Jingzhe (Awakening of Insects) among the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, etymological origins, astronomy, and phenology. Through an examination of the historical renaming from 'Qizhe' to 'Jingzhe,' an analysis of how spring thunder rouses hibernating creatures, and the cosmic vision of the Zhen (Thunder) hexagram's 'the sovereign emerges from Zhen' in the Book of Changes, the essay reveals the critical threshold at which life transitions from dormancy to vigorous action, illuminating the ancient Way of bending and stretching to preserve one's being.
Chapter Six: The Dazhuang Hexagram -- Four Yang Lines Ascendant; the Noble Person Does Not Tread Where Propriety Forbids
I. The Dazhuang Hexagram: The Second Month in the Twelve Waxing-and-Waning Hexagrams
Beyond the Zhen trigram, understanding Jingzhe requires yet another indispensable hexagram image -- Dazhuang (Great Vigor). This involves a vitally important system in the Book of Changes: the Twelve Waxing-and-Waning Hexagrams (shi'er xiaoxi gua).
The Twelve Waxing-and-Waning Hexagrams correlate twelve hexagrams with twelve months, illustrating the process of yin-yang waxing and waning over the course of a year. "Waning" (xiao) refers to the growth of yin and decline of yang; "waxing" (xi) refers to the growth of yang and decline of yin. These twelve hexagrams, read from bottom to top, use the gradual increase of yang lines (or yin lines) to represent the waxing and waning of yang qi, forming a complete picture of yin-yang alternation:
Eleventh month: Fu (Return, one yang born at the bottom); twelfth month: Lin (Approach, two yang lines); first month: Tai (Peace, three yang -- "Three Yangs Usher in Auspiciousness"); second month: Dazhuang (Great Vigor, four yang lines ascendant); third month: Guai (Breakthrough, five yang lines); fourth month: Qian (Heaven, six yang, pure yang) -- after which yin qi begins to sprout -- fifth month: Gou (Encounter, one yin born); sixth month: Dun (Withdrawal, two yin); seventh month: Pi (Stagnation, three yin, three yang); eighth month: Guan (Contemplation, four yin ascendant); ninth month: Bo (Stripping, five yin stripping yang); tenth month: Kun (Earth, six yin, pure yin).
The second month (Month of Mao) in which Jingzhe falls corresponds precisely to the Dazhuang hexagram. Dazhuang is composed of four yang lines below and two yin lines above. In terms of the hexagram image, yang qi has grown to four lines -- a situation of yang qi "ascendant in vigor." After the Fu hexagram's return of one yang, the Lin hexagram's two yang, and the Tai hexagram's three yang, by the time we reach the second month's Dazhuang, yang qi has seized an overwhelming advantage in the lower four positions and is pushing upward with unstoppable force. This is the most fitting hexagram portrait of Jingzhe's surging yang qi, earth-shaking thunder, and the rising of all things.
II. "Thunder above Heaven, Great Vigor": The Image of Thunder Soaring above the Sky
The structural image of the Dazhuang hexagram itself is replete with the resonance of Jingzhe. The lower trigram of Dazhuang is Qian (Heaven, ☰), and the upper trigram is Zhen (Thunder, ☳). Thus Dazhuang is also called "Thunder above Heaven" (lei tian dazhuang).
The Image commentary of the Dazhuang hexagram states: "Thunder above heaven -- Great Vigor." Imagine the scene: thunder, that surging yang qi, has risen above heaven itself, crashing and reverberating, awe-inspiring in all directions. Compared with the Zhen trigram (thunder rising from beneath the earth), this represents a further stage -- in Zhen, yang qi has just broken through the surface, while in Dazhuang, it has ascended to the sky, its momentum even grander and more vigorous.
This precisely corresponds to the evolution of yang qi from Lichun (Beginning of Spring) to Jingzhe. At Lichun, yang qi has just stirred, still germinating underground. By Jingzhe, yang qi has grown strong enough to burst through the surface, manifest as thunder, and shake heaven and earth -- this is "Great Vigor," this is "Thunder above Heaven." The lower trigram Qian (Heaven, pure yang) represents a resolute, upward-moving force; the upper trigram Zhen (Thunder, movement) represents a surging, shaking force. Together they present a scene of yang ascendancy, robust vitality, and irrepressible momentum.
Why is this hexagram called "Great Vigor" (Dazhuang) and nothing else$40 The Tuan (Judgment) commentary explains: "Great Vigor: what is great is vigorous. Strength moves, hence vigor." "Great" (da) refers to yang -- yang is great, yin is small. "What is great is vigorous" means yang qi has grown strong. "Strength moves, hence vigor" -- the virtue of firm strength (Qian) combined with the momentum of vigorous movement (Zhen) produces "vigor." This is exactly the spirit of Jingzhe: yang qi (the great) has become vigorous; firm and striving, irresistible.
III. "The Noble Person Does Not Tread Where Propriety Forbids": Restraint amid Vigor
Yet the deepest wisdom of the Dazhuang hexagram lies not in its description of "vigor" but in its admonition regarding vigor. The Great Image commentary delivers a supremely pointed statement: "Thunder above heaven -- Great Vigor; the noble person does not tread where propriety forbids" (junzi yi fei li fu lu).
What does this mean$41 Thunder above heaven, yang qi ascendant -- this is the image of Great Vigor. Upon observing this image, the noble person should refrain absolutely from doing anything that violates propriety (li, ritual propriety) -- "lu" meaning to walk, to practice, to do.
What profound insight! Why must one emphasize "not treading where propriety forbids" precisely when yang qi is at its most vigorous$1
Because "vigor" is a double-edged sword. Vigorous yang qi means abundant vitality and overflowing strength -- a good thing. But at the peak of vigor, one is most prone to excess, to violence, to recklessness. The stronger the force, the more tempting it is to abuse it. The more surging the energy, the more easily it spins out of control into destruction. Therefore, it is precisely at the moment of "Great Vigor" -- when strength is at its peak -- that the noble person must exercise the highest self-restraint and self-discipline, using "propriety" (li) to regulate all speech and conduct, and absolutely refusing to do anything that violates it.
This reveals a profound dialectic: power and restraint. True "vigor" is not the brute force that charges forward heedless of all else, but force constrained by propriety, a force that knows what to do and what not to do. The Tuan commentary adds: "Great Vigor is favorable when correct. What is great must be correct. Correct and great -- and the true nature of heaven and earth can be discerned." True greatness must have "correctness" (zheng) as its prerequisite. Only greatness that is upright, open, and in accord with propriety and righteousness is worthy of affirmation; otherwise, vigor without rectitude degenerates into disorder.
At Jingzhe, this wisdom is most needed. At the year's start, with yang qi surging and all things rising, one is full of eager ambition -- and rightly so. But precisely at such moments of high spirits and abundant energy must one understand the principle of "not treading where propriety forbids": this surging force must be channeled into the track of propriety, becoming constructive and measured rather than being allowed to run wild. This is the solemn admonition that the Dazhuang hexagram offers to Jingzhe and to every person who strives forward: strength must be tempered; vigor must be grounded in rectitude.
IV. The Combined Reading of Zhen and Dazhuang: The Twofold Hexagram Wisdom of Jingzhe
We have now seen that Jingzhe is linked to two hexagram images in the Book of Changes: the Zhen trigram ☳ as the fundamental trigram of thunder, and the Dazhuang hexagram as the waxing-and-waning hexagram of the second month. These two hexagrams, from different angles, together reveal the deeper wisdom of Jingzhe.
The Zhen trigram tells us "the sovereign emerges from Zhen" -- Jingzhe's thunder is the beginning of cosmic life, the activation of creative force. It also tells us "repeated thunder, the noble person is moved to fearful self-examination" -- before heavenly majesty, one should be awed and self-reflective. And it tells us "thunder startles for a hundred li, yet he does not lose the ladle and libation" -- constancy in the face of upheaval.
The Dazhuang hexagram tells us "Thunder above Heaven, Great Vigor" -- at Jingzhe, yang qi is ascendant and irrepressible. It also tells us "the noble person does not tread where propriety forbids" -- amid vigor there must be restraint; strength must be channeled within the track of propriety. And it tells us "what is great must be correct" -- true greatness must have rectitude as its premise.
Viewing these two hexagrams together, we arrive at a complete, dialectical life wisdom: on one hand, follow the "movement" -- accord with the surging of yang qi, actively engage, and throw oneself into life's labor. On the other hand, maintain "measure" within that movement -- exercise self-discipline through propriety, hold firm amid change. To move with measure, to be vigorous yet correct, to strive yet remain self-aware -- this is the core spirit that Jingzhe conveys through the two hexagrams of the Book of Changes. It is by no means a simple encouragement to "rise up" but rather, while encouraging rising, an earnest admonition to understand restraint and rectitude. This profoundly dialectical wisdom is what makes ancient Chinese philosophy most precious.
