Year II F, Month VII E, Day VII G (Void: L and M)
Stars and Omens: Traveling Horse Star: J

In China, during the nationwide travel peak of the May Day holiday, one usually needs to rush in advance to secure train or high-speed rail tickets. Before last year’s May Day holiday, a friend of mine was scrambling frantically to get a ticket home and came to ask me for a divination. He wanted to see whether he could obtain a waitlisted ticket home. Therefore, he could plan the rest of his trip. He obtained Guan to Wu Wang.

Judgment: When asking about tickets, documents, and similar credentials, the parents line is taken as the significator line. The parents line shows Dual Appearance[1] in the hexagram. Both the host line and the corresponding line are parents H earth, and both are active, so priority is given to the host line as the significator line. The significator line, H earth, receives peer support from the monthly branch E and is prosperous and supportive. Moreover, it is itself active and transforms into the officials and ghosts line, G fire. This forms a return generation, since G fire generates H earth. Its overall strength is very strong. Therefore, this indicates that the ticket could be secured.

Year X D, Month IX L, Day II F (Void: C and D)

A recent graduate asked whether he would pass the interview and whether he would be notified to start work. The hexagram obtained was Kan to Kun.

Judgment: The host siblings line, A water, is overcome by the monthly branch L and is in extinction on the daily branch F. Moreover, the host line, A water, is in the state of dead in the month of L. In addition, it coincides with the Black Tortoise, indicating that the querent himself had only average ability and was not flexible enough. The host A line and the corresponding G line being in clash also indicates that the job seeker and the requirements of this work unit did not match.

1. The parents J metal line is active and generates the host line, but it is bound in compatibility by the daily branch F (the daily branch here represents the interviewer or leader). This indicates that the querent originally seemed to have some chance. However, in the end he might still be screened out.
2. The primary hexagram, Kan as Water, is a Six Clashes Hexagram, representing difficulty and stoppage. The transformed hexagram, Kun, is a Six Compatibles Hexagram, which would ordinarily be a favorable sign. However, the host line is weak and is overcome in multiple ways. So this is still not enough to change the result. In judging the hexagram, one must still primarily look at the host line and the significator line.
3. The parents J metal line, which represents the interview or offer, is solitary active. Although it is active and generates the host line, it transforms into the siblings line, M water. The transformed line is broken (clashed by the F daily branch). This indicates that it would not work out, and also suggests that someone else passed. The siblings line can represent peers, and it can also represent competitors. In hexagrams involving competition, the siblings line holding the host is unfavorable for achieving the intended goal. For example, when seeking wealth, if the siblings line holds the host, it indicates that it is difficult to obtain wealth. What is even more problematic is when the siblings line is active, except in cases where the descendants line is also active. This is because this then forms a pattern in which the active siblings line generates the descendants line. Furthermore, the active descendants line generates the wife and wealth line. Instead, this is favorable when seeking wealth.

Conclusion: He would not pass the interview.

Feedback: On October 17, the querent reported that he had not passed. The reason was that the work unit believed that he had just graduated, lacked experience, and was not stable enough. The position was an administrative one, and the work unit wanted to hire someone experienced and stable.

Year I E, Month VI F, Day VII E (Void: J and K)

A man asked about reconciling with his ex-girlfriend. The hexagram obtained was Gou to Huan.

Judgment: The primary hexagram is Gou, which is highly inauspicious for a man asking about a relationship. There are two analytical angles for determining the significator line in this case:

1. For a man, the wife and wealth line, C wood, is taken as the significator line. The significator wife and wealth line is in the states of rest and constraint, coincides with the Black Tortoise, is hidden beneath, and is compatible with the flying line, M water. This indicates that there should be someone else around the ex-girlfriend.
2. If analyzed from the perspective of the host and corresponding lines, the host line represents the man himself, and the corresponding line represents the woman. If the woman, represented by the corresponding line, is taken as the significator line, then the officials and ghosts line, G fire, is active and transforms into the parents line, H earth, in compatibility. Compared with the host line, B earth, H earth represents another man. The top line, L earth, is clashed by the daily branch and shows covert activation, which also points to another man. This corresponds to the analysis of taking the wife and wealth line as the significator line. The hidden wife and wealth line being compatible with the descendants line, M water, also indicates that she has other choices. All of this shows that this woman likely does not lack potential partners around her.

The siblings line, K metal, between the host and corresponding lines is active and forms an obstruction. The activation of K metal can also represent a competitor. This means that even if they reconcile, the woman may still later be taken by someone else. The second line, the Black Tortoise descendants line, M water, is monthly broken and overcome by the daily branch, fallen and without root. The source god of the host line, G fire, which is also the corresponding line, is in harm with the host line. This indicates that even if the two are together, they would not really be happy. There is also a feeling of knowing that it should not be done, yet still doing it.

Feedback: She is still in school. Whenever she goes home during school breaks, she stops responding to the querent. The querent does not know her situation very well, but she is always somewhat mysterious. However, she really does get along quite well with the boys in her class.

This does indeed match the analysis. As for how to choose, that is the querent’s own decision. But if the hexagram had already shown so clearly that the relationship was obstructed and unlikely to bring happiness, was reconciliation ever really possible?

I. Twelve Stages of Life

1.2.3.2: Methods of Applying Tomb and Storehouse

In Six Lines Divination, the tomb/storehouse positions are as follows. These positions also play an important role in I Ching Divination:

• Metal enters the tomb at B
• Fire enters the tomb at L
• Wood enters the tomb at H
• Water and earth enter the tomb at E

A line enters the tomb in the following cases:

• when it encounters the tomb/storehouse of the daily branch or monthly branch
• when it self-transforms into a tomb/storehouse line
• when it encounters an active tomb/storehouse line
• when it is hidden beneath a tomb/storehouse line

There are several points to note:

• Daily tomb is commonly used, while monthly tomb can be used in image-based interpretation. The two are different.
• Only true self-transformation into tomb counts as transformation into tomb. For example, water transforming to E counts, while fire transforming to E does not.
• When a tomb/storehouse line is active and an adjacent line enters the tomb, this is mostly used for determining imagery and timing.
• When a hidden line enters the tomb, this refers to the flying-hidden relationship. If fire is hidden beneath E, B, or H, and similar cases, this is not entering the tomb, because L is the tomb of fire. It only means that tomb/storehouse and concealment share similar imagery.
• There are also three cases of following the officials and ghosts line into the tomb: the body line, the host line, and the natal line following the officials and ghosts line into the tomb. In modern practice, this is rarely used, but it can still be applied in image-based interpretation.

I. Twelve Stages of Life

1.2.3.1: Methods of Applying Birth, Peak, Tomb, and Extinction

We already know some of the symbolic meanings of Birth, Peak, Tomb, and Extinction. When using I Ching Divination, how should we apply them in actual practice?

First, we need to understand the following concepts:

• a line can encounter Birth, Peak, Tomb, or Extinction through the daily branch
• a line can encounter Birth, Peak, Tomb, or Extinction through an active line
• a line can encounter Birth, Peak, Tomb, or Extinction through a transforming line

Note:

It is enough just to know that this concept exists.

Generation amidst extinction:

When a hexagram line encounters a place of death, if there is another nearby line that comes to generate it, then this is regarded as false death, and is called “generation amidst extinction.”

The image of death:

It carries the meanings of death, getting stuck in a dead end, inflexibility, inability to adapt, stagnation, termination, being finished, rigidly clinging to one view, going down one road all the way to the end, having no room left, downturn, lack of vitality, lifelessness, dullness, clumsiness, being unable to let go, narrow-mindedness, having no way out, silence, stillness, and fearfulness.

Transforming into a place of death:

Metal (J and K) transform into A water.
Fire (F and G) transform into K metal.
Wood (C and D) transform into G fire.
Earth (E, H, L, B) and Water (M and A) transform into D wood.

I. Twelve Stages of Life

1.2.2 The Meanings of Birth, Peak, Tomb, and Extinction

Birth: Birth symbolizes a person who has just been born. This is an auspicious sign. In I Ching Divination, it represents something that is about to grow and become stronger, and its meaning is very close to what will later be discussed as advancing god.

For example, when divining the weather, the parents line represents rain. If it coincides with Birth and is not damaged, it indicates that rain may continue for several days. It will keep raining for quite a long time. Birth, after all, means a beginning, something newly born, with many days still ahead. That is the idea it conveys.

Peak: Peak symbolizes a person in the prime of life, around seventeen, successful in career, flourishing, and full of confidence. Its meaning follows the same principle as prosperity under the monthly branch, though there are differences in degree, so they should not be treated as exactly the same.

This will also be explained in detail in our video course, and the notes will later be organized and added here as well.

Tomb: Tomb means that after a person dies, they are buried in a grave. In practical divination, Tomb generally represents concealment, stagnation, and hardship. When someone is sick and hospitalized, or when someone has broken the law and is imprisoned, this sign often appears. Freedom has been restricted, and one is trapped within a narrow space. That is the meaning of Tomb.

Extinction: Extinction symbolizes the state after death, when both physical form and spirit are gone. Extinction is an unfavorable factor in a hexagram. However, its force is not as strong as generation and overcoming. Therefore, in prediction, it is only an auxiliary factor and cannot by itself be used to determine auspiciousness or inauspiciousness.

1.2 Core Life Stages in Liuxiao Prediction

Among the Twelve Stages of Life (Twelve Life Cycles), practical I Ching Divination/Six Lines Divination primarily utilizes four specific stages. These represent the most critical shifts in energy and timing. Memorizing these four is essential for any practitioner:

1. Birth
2. Peak
3. Tomb (also known as Grave or Storehouse)
4. Extinction

4.6. Na Yin in Na Jia Timing

How the Sixty Jia Zi Elemental Sound System Works, the Full 30 Pair Chart, and Why It Matters in Wen Wang Gua Interpretation

 In Na Jia timing for Wen Wang Gua, you already track the stem branch time markers (year, month, day, hour). When studying topics like I Ching Divination, Na Yin adds a second layer of elemental quality and imagery that can sharpen interpretation, especially when you want a clearer feel for the “texture” of a time period rather than only its raw Five Element label.

Na Yin (Elemental Sound System) is traditionally said to originate very early, and later became standardized as part of the Sixty Jia Zi system. In some traditional accounts it is attributed to Guiguzi, with the naming associated with Dongfang Shuo.

Early records show Na Yin used primarily as a Five Element assignment, without the later, richer imagery. In other words, you see statements like “jia zi, yi chou are metal” or “bing yin, ding mao are fire.” Later, especially by the early Song period, imagery labels such as “Metal of the Sea” or “Fire of the Furnace” became common, making the system easier to remember and more expressive for interpretive work.

Each Na Yin pair has both an element and an image, and the image is not decorative, it often hints at strength, quality, and behavior of that element. Below are compact interpretive notes aligned with your source material.

1. Metal of the Sea (I A, II B)
   Water is strong here, metal is “stored” and submerged, so it can feel hidden, constrained, or contained, like metal concealed within deep water.
2. Fire of the Furnace (III C, IV D)
   Fire is well positioned and fed by wood, like a cosmic kiln at the beginning of creation, strong generative heat that initiates growth.
3. Wood of the Great Forest (V E, VI F)
   A lush, expansive wood in open terrain, vigorous and far reaching, but it dislikes being overwhelmed by strong stream or sea water forces.
4. Earth by the Roadside (VII G, VIII H)
   Soil that is trampled and shaped for passage, thick but not primarily for nurturing life, it can support certain woods but may not favor overly “wild forest” qualities.
5. Metal on the Sword’s Edge (IX J, X K)
   Metal in its true position, sharpened and hardened, decisive, cutting, and clear, like a blade with cold brilliance.
6. Fire on the Mountain Peak (I L, II M)
   Fire rising high at a “gate of heaven,” visible and far reaching, like sunset light across a ridge, intense but often more about illumination than warmth.
7. Water under the Stream (III A, IV B)
   Water that peaks then wanes, not a grand river, more like clear ravine flow among mountains, clean, swift, and contained.
8. Earth on the City Walls (V C, VI D)
   Earth piled into defensive structure, elevated and protective, with an imperial, fortified quality, solid containment and boundary.
9. Metal of White Wax (VII E, VIII F)
   Metal that is forming but not yet fully hard, delicate and pliable, like metal taking shape at twilight where yin yang meet.
10. Wood of the Willow (IX G, X H)
    Wood weakened by its position, softened but sustained by water support, flexible, fine, and continuous, like threads that do not break.
11. Water from the Well (I J, II K)
    Water born from metal strength, but not yet vast, quiet, steady, and inexhaustible in a contained way.
12. Earth on the Roof (III L, IV M)
    Earth shaped by rising fire, not ground soil but elevated earth, stronger through fire wood support, and it prefers quiet stability.
13. Fire of the Thunderbolt (V A, VI B)
    Fire within water and earth interplay, sudden, electric, and transformative, like lightning that can shift conditions rapidly when the environment supports it.
14. Wood of Pine and Cypress (VII C, VIII D)
    Wood at its strongest, towering, enduring, and resilient, with a “snow and frost” presence, steady power that outclasses softer woods.
15. Water of Long Flowing (IX E, X F)
    Reservoir water meets metal’s birth, a spring that does not run dry, quiet but continuous, favoring stillness and sustained flow.
16. Metal in the Sand (I G, II H)
    Fire is strong, metal is challenged, sand metal is granular and dispersed, not easily consolidated without the right conditions.
17. Fire under the Mountain (III J, IV K)
    Light that is concealed at a gate or setting point, stored brilliance, it may reemerge and brighten again with the right directional support.
18. Wood of the Flatlands (V L, VI M)
    Wood born in open fields, it prefers nourishment from rain and dew, and dislikes harsh frost or snow forces.
19. Earth on the Wall (VII A, VIII B)
    Earth mixed with abundant water into mud, enclosing and concealing, it stores and hides substance, but can feel blocked or internally sealed.
20. Metal of the Leaf (IX C, X D)
    Metal weakened in strong wood terrain, thin like foil or leaf metal, light, delicate, and easily shaped, not forceful.
21. Fire of the Buddha Lamp (I E, II F)
    Fire at a bright threshold, refined light that illuminates what ordinary sunlight misses, a clear, focused radiance.
22. Water of the Heavenly River (III G, IV H)
    Water drawn from fire positioning, elevated and vast like a celestial river, it can nourish widely when strong, and should be able to rise and fall in movement.
23. Earth of the Grand Station (V J, VI K)
    Earth of transport and storage, heavier and more substantial than thin soil, a gathering and resting place where qi returns and things are collected.
24. Metal of Hairpin and Jewelry (VII L, VIII M)
    Metal already shaped into ornament, soft but valuable, it favors conditions that strengthen and preserve it, and it benefits from supportive growth.
25. Wood of Mulberry (IX A, X B)
    New wood emerging in water territory, meeting metal “cutting,” it implies shaping, pruning, and the early stage before full expansion.
26. Water of the Grand Creek (I C, II D)
    Water flowing in the true eastern direction, gathering streams and pools into a coherent current, more forceful than small ravine water.
27. Earth of the Sand (III E, IV F)
    Earth stored then depleted, fire returns to generate it again, granular, shifting, needing consolidation to become truly stable.
28. Fire of the Sky (V G, VI H)
    Fire blazing upward, radiant and expansive, a strong yang flame quality that is broad, visible, and hard to contain.
29. Wood of the Pomegranate (VII J, VIII K)
    Wood reviving in metal season, quiet, focused, gradually producing treasure, with autumn fruit maturity as its image.
30. Water of the Great Sea (IX L, X M)
    Deep, vast water power, expansive and oceanic, it can be restrained when supported properly, and it behaves differently from lesser waters.

How to apply Na Yin in Na Jia timing for Wen Wang Gua

Use Na Yin as a secondary timing lens that refines the “quality” of a time marker after you already identify the standard stem branch element relations. A clean workflow looks like this:

1. Identify the year, month, day, or hour Jia Zi used in your reading.
2. Look up its Na Yin pair and record the Na Yin element and image.
3. Compare that Na Yin element against the structure you are already judging (support, overcome, generation patterns).
4. Use the image label as a narrative constraint, it helps you avoid overgeneralizing a plain “water, fire, wood” reading.

In practice, Na Yin is most helpful when multiple factors look mixed and you need an extra “tie breaker” to describe what kind of wood, what kind of water, or what kind of metal the time is expressing. For example, “Water of the Great Sea” and “Water from the Well” are both water, but they imply very different scale, behavior, and containment.

Where stem branch imagery fits in the bigger system

Na Yin is only one part of building strong timing intuition, and the imagery logic of stems and branches themselves also matters.
