Core Symbolism

In the Biting Through hexagram, the upper trigram Li represents Fire and clarity (Ming), while the lower trigram Zhen represents Thunder and movement (Dong). Thunder and lightning act together, bringing both majestic authority and illuminating insight. The image is akin to clenching teeth to bite through hard matter, removing obstruction to regain smooth passage. In human affairs, this corresponds to litigation, arbitration, eliminating wickedness, and rectifying malpractices. It emphasizes perceiving subtleties, administering law with dignity, combining firmness with flexibility, and surmounting hindrances. Simultaneously, it warns against excessive harshness in punishment, as well as undue leniency—the need is for upright, balanced, and clear judgment.

The six lines of the hexagram unfold around the themes of removing obstruction and deciding legal cases. The First Nine shows minor penalties for major prevention. The Six in the Second indicates smooth administration and easily removing the wicked. The Six in the Third encounters malicious resistance but ends without major fault. The Nine in the Fourth, through steadfastness in hardship, attains auspiciousness by eliminating obstacles. The Six in the Fifth, residing in the honored position, uses punishment centrally and with insight, incurring no blame. The Top Nine shows accumulated evil and severe transgression leading to misfortune. The overall core themes are clarifying punishments and reforming laws; firm, clear-sighted judgment; and the removal of obstacles.

Classical Texts (Guji Yuanwen)

Hexagram and Line Texts (Gua Ci & Yao Ci)

噬嗑: 亨。利用狱。 初九: 屦校灭趾,无咎。 六二: 噬肤灭鼻,无咎。 六三: 噬腊肉,遇毒;小吝,无咎。 九四: 噬干胏,得金矢,利艰贞,吉。 六五: 噬干肉,得黄金,贞厉,无咎。 上九: 何校灭耳,凶。

Commentary on the Judgement (Tuan Zhuan)

《彖》曰:颐中有物,曰噬嗑。噬嗑而亨,刚柔分,动而明,雷电合而章。柔得中而上行,虽不当位,利用狱也。

Interpretation: If something in the mouth requires biting through, it is called "Biting Through." Biting through leads to success. The firm and the yielding are separated, action is combined with clarity, thunder and lightning unite and display their splendor. The yielding line attains the central position and moves upward; although it does not hold its proper place, it is beneficial for practicing legal judgment.

Commentary on the Images (Xiang Zhuan)

《象》曰:雷电噬嗑。先王以明罚敕法。

Interpretation: Thunder and lightning combine to form the Biting Through hexagram. The ancient kings, in accordance with this image, clarified punishments and reformed laws to govern the world.

《象》曰:

  • 屦校灭趾,不行也。
  • 噬肤灭鼻,乘刚也。
  • 遇毒,位不当也。
  • 利艰贞吉,未光也。
  • 贞厉无咎,得当也。
  • 何校灭耳,聪不明也。

Interpretation: "Wearing foot-shackles that cover the toes"—this is to prevent further evil conduct. "Biting through soft flesh covering the nose"—this means relying on the firm line to eliminate the wicked. "Encountering poison"—the position is inappropriate. "Beneficial to remain steadfast in hardship. Good fortune"—his virtue and deeds are not yet fully developed. "To remain steadfast is perilous, yet no blame"—the application of punishment is proper and fitting. "Bearing a cangue that covers the ears"—his hearing (discernment) is not clear; he does not heed good advice, and evil accumulates unchanged.

Is Hexagram 21 Biting Through primarily auspicious or inauspicious?

In what situations is Hexagram 21 Biting Through appropriate?

Answer: It is suitable in scenarios involving litigation, arbitration, law enforcement and discipline, rectifying malpractices, and clearing blockages. It is not suitable for situations that indulge wrongdoers, apply excessively harsh punishment, or involve rash, unconsidered judgments.

What guidance does receiving Hexagram 21 offer regarding disputes and lawsuits?

Answer: One should clearly perceive right and wrong and make judgments in accordance with the law. Among the lines, the Nine in the Fourth and Six in the Fifth, emphasizing steadfastness and clear-sightedness, are most auspicious.

FAQ

What does the Biting Through hexagram fundamentally symbolize?

The hexagram Biting Through symbolizes the decisive act of biting through a hard obstruction to unblock a path. It represents themes of legal adjudication, administering just punishments, resolving disputes, and the necessary combination of force (thunder) and clarity (fire) to overcome obstacles. The core principle, derived from the Great Image, is that ancient kings used this concept to clarify punishments and reform laws.

Is Hexagram 21 considered generally auspicious or inauspicious?

Biting Through is classified as a moderately auspicious hexagram. Its judgment states "Success. It is favorable to practice legal judgment," indicating that positive outcomes arise from applying its principles of decisive action and lawful resolution. However, its auspiciousness is contingent on exercising firm yet wise judgment, as depicted in the lines, where improper or stubborn conduct can lead to misfortune.

How do the component trigrams, Fire (Li) and Thunder (Zhen), contribute to the meaning?

The upper trigram, Li (Fire ☲), provides clarity, insight, and the illuminating quality needed to discern truth in judgments. The lower trigram, Zhen (Thunder ☳), supplies the dynamic force, shock, and activating power required to execute decisions and remove blockages. Together, they create the image of "thunder and lightning," combining majestic action with brilliant understanding to bite through difficulties.

What is the key lesson from the line about "biting on dried gristly meat and finding a metal arrowhead" (Nine in the Fourth)?

This line signifies encountering an extremely tough and persistent obstacle (the gristly meat). Discovering the "metal arrowhead" within it symbolizes uncovering a tool of truth or justice—such as clear evidence—in the midst of hardship. The lesson is that perseverance in adhering to what is right and lawful, even in difficult circumstances, ultimately leads to good fortune and the means to break through.

While it originates from ancient legal concepts, the principle applies broadly today. It advises bringing clear, firm, and just resolution to any situation of conflict, obstruction, or entangled interests. This could mean formal litigation, arbitration in business, enforcing fair rules within a team, or even making a difficult personal decision that "severs" a problematic tie to restore order and progress.

Why does the top line ("Wearing a cangue that hides the ears") result in misfortune?

The top line represents the culmination of obstinate wrongdoing. The "cangue" is a heavy wooden pillory, and hiding the ears symbolizes a willful refusal to listen to reason, warnings, or the law. The misfortune results not merely from the severity of the punishment but from the individual's complete incorrigibility and the extreme nature of their offenses, leaving no alternative to severe sanction.

Can Biting Through relate to personal internal struggles?

Yes. While often applied to external conflicts or legal matters, the hexagram can symbolize the internal process of "biting through" a hard personal barrier. This could be a stubborn habit, a deeply held resentment, or a mental block. The process requires the internal "clarity" (Fire) to see the issue clearly and the "dynamic force" (Thunder) to take decisive action to resolve it and move forward.

How does the concept of "combining firmness and flexibility" manifest in this hexagram?

The structure of the hexagram itself interweaves firm (yang) and yielding (yin) lines. In practice, this means justice should be firm in principle but flexible in its consideration of circumstances (as seen in the gradations of punishment in the lines). Successful "biting through" requires the strength to act decisively, combined with the discernment to apply appropriate force—neither too harsh nor too weak.
