Hexagram 21: Biting Through
䷔ 噬嗑 Shì Kè – The Book of Changes
The Judgment
Biting Through indicates successful progress. It will be advantageous to use legal constraints.
The Image
Thunder and lightning: the image of Biting Through. Thus the ancient kings framed their penalties with intelligence and promulgated their laws.
Description
Biting Through (Shi He) shows a mouth with something stuck between the teeth: an obstacle that blocks union and must be bitten through. Thunder and lightning combine force and clarity. The figure calls for energetic, fair intervention and clear rules, not endless tolerance of what is wrong.
The six lines
A line's place shapes its role: 1 the beginning, 2 the center of the inner world, 3 the threshold to the outside, 4 close to power, 5 the ruler's place, 6 the end and the excess. Keep this grid in mind and the line texts become much easier to read. More in the guide →

Reading by area of life
❤️ What does hexagram 21 mean for relationships and private life?
An obstacle stands between you and someone close: a lie, a habit, an outside influence, a repeatedly broken promise. Ignoring it no longer works. Address it directly and specifically, and agree on clear consequences if it continues. Be firm but fair; the aim is to remove the obstacle, not to punish the person. Clarity now restores the closeness that has been blocked.
💼 What does hexagram 21 mean for work and money?
Time to deal with obstruction head-on. Contract breaches, unpaid invoices, a colleague who undermines the team, bureaucratic deadlock: each calls for decisive action, documented and within the rules. Legal or formal steps may be justified. Get the facts straight before acting, then act without hesitation. Clear policies and consistent enforcement prevent the same blockage from forming again.
🌌 What does hexagram 21 mean for your personal path and spirituality?
Inwardly, something has to be chewed through: a self-deception, an addiction, a fear you keep circling. Half-measures leave it lodged where it is. Name it clearly, set yourself rules you can keep, and follow through. Lightning brings clarity, thunder brings resolve; you need both. Discipline grounded in understanding is not harsh; it frees energy that has been stuck for a long time.
Nuclear hexagram
Lines 2, 3 and 4 form the lower trigram, lines 3, 4 and 5 the upper one. Leaving out the beginning and the end reveals the core of the situation, what is at work out of sight. It is a secondary aspect, not a second verdict. If it seems to contradict the main hexagram, that happens and is not an error. More in the guide →
Lines 2, 3, 4 and 3, 4, 5 form nuclear hexagram 39, Obstruction. It shows what is at work beneath the surface – an inner tendency, not a verdict on the situation itself.
Hexagram 39 – Obstruction
In Obstruction advantage will be found in the southwest, and the contrary in the northeast. It will be advantageous also to meet with the great man. In these circumstances, with firmness and correctness, there will be good fortune.
The two trigrams
- Upper, outer: Li – Fire
- The Clinging (Middle Daughter). Within, it is clarity, inner vision and passion; without, a light that guides and connects through beauty and meaning.
- Lower, inner: Zhen – Thunder
- The Arousing (Eldest Son). Within, it is the impulse to change, to wake up and break free; without, a sudden jolt that shatters rigidity and sets things moving.
