Hexagram 35 Fire Over Earth (Jin, 晉): Advancing, Rising, and the Six Line Texts of the I Ching

What is Hexagram Hoa Dia Tan and where does it sit among the 64 hexagrams?

Hoa Dia Tan (火地晉), usually shortened to hexagram Tan, is the 35th of the 64 I Ching hexagrams in the King Wen sequence. The hexagram consists of the inner (lower) trigram Khon ☷, image of earth, and the outer (upper) trigram Ly ☲, image of fire and the sun. Its core image is the sun rising above the earth, shining everywhere. The character 晉 (tan) means to advance, to move forward.

In Wikipedia's listing of the 64 hexagrams, hexagram 35 carries the Unicode symbol ䷢, inner trigram Khon, outer trigram Ly. The naming convention places the outer trigram first and the inner trigram second, giving the name Hoa Dia Tan. Some Vietnamese sources list this hexagram as number 34, which comes from a numbering offset; in the standard King Wen sequence, Tan is hexagram 35. This article follows the King Wen sequence, so Tan is hexagram 35.

In terms of yin and yang structure, the hexagram has two yang lines (lines 4 and 6) and four yin lines. Yin lines are many and yang lines few, but the yang lines sit high and bright, creating a stance of "few yet shining." This is worth noting when interpreting: Tan is not a hexagram of overwhelming majority but of light that is seen.

The upper and lower trigrams and the names of the six lines

The six lines of hexagram Tan, read from the bottom up, are:

• So luc (line 1, yin)
• Luc nhi (line 2, yin)
• Luc tam (line 3, yin)
• Cuu tu (line 4, yang)
• Luc ngu (line 5, yin)
• Thuong cuu (line 6, yang)

Line names follow the rule that yin lines are called "luc" and yang lines "cuu," with a number counted from the bottom up. This convention lets readers locate a line within the hexagram without memorizing the whole diagram.

What do the Judgment and the Image of hexagram Tan say?

The Judgment (Thoan tu) of hexagram Tan is recorded in the HOROS source as:

"晉：康侯用錫馬蕃庶，晝日三接"

Sino-Vietnamese reading: "Tan: Khang hau dung tich ma phien thu, tru nhat tam tiep."

Meaning: the Marquis of Khang was granted countless horses and was received by the king three times in a single day. The image speaks of someone whose merit is clearly recognized: abundant rewards and the trust of those above. The HOROS source stresses that advancement here does not come from contention but from harmony between those above and those below.

The Image text of the hexagram:

"明出地上，晉。君子以自昭明德"

Sino-Vietnamese reading: "Minh xuat dia thuong, Tan. Quan tu di tu chieu minh duc."

Meaning: light rises above the earth; this is the image of Tan. The noble person accordingly makes their own bright virtue shine. Notably, the Image does not say to wait for others' recognition but to shine from within. This is the moral layer that the Confucian tradition assigns to the hexagram.

Why does hexagram Tan follow hexagram 34?

In the Sequence (Tu Quai), hexagram 34 is Loi Thien Dai Trang, meaning great strength and prosperity. Once one has grown strong, advancing is inevitable, so Tan follows. This explanation is common in traditional I Ching books: Dai Trang is the stance of sufficient strength, Tan is the step that uses that strength to move forward. The Ly so Viet Nam source, discussing the meaning of the 64-hexagram order, also presents the principle of succession as "prosperity then advance," meaning each preceding hexagram sets the premise for the next. Note that this is a traditional reading of the Sequence, not a mandatory formal rule.

The six line texts of hexagram Tan and plain-language explanations

The six line texts below are transcribed from the Chinese and Sino-Vietnamese in the HOROS source, with interpretation.

So luc: advancing yet blocked

Original: "晉如，摧如，貞吉。罔孚，裕無咎"

Sino-Vietnamese: "Tan nhu, toi nhu, trinh cat. Vong phu, du vo cuu."

Meaning: advancing yet blocked; holding firm is good. Not yet trusted; being generous brings no fault.

This is the lowest line, matching a stage of just beginning to be noticed but not yet truly trusted. Proposals are rejected, ideas go unheard, results are unrecognized. The line advises keeping a generous attitude and not showing resentment. The HOROS source interprets: one who does good work quietly will eventually be seen.

Luc nhi: advancing yet anxious

Original: "晉如，愁如，貞吉。受茲介福，于其王母"

Sino-Vietnamese: "Tan nhu, sau nhu, trinh cat. Thu tu gioi phuc, vu ky vuong mau."

Meaning: advancing yet sorrowful; holding firm is good. Receiving great blessing from the royal grandmother.

The image of the "royal grandmother" here means blessing coming from a yin and yielding source above, namely line 5. In the context of ancient society, the image of the grandmother is tied to authority within the clan; this is a social norm of the past and should not be read as advice for modern life. The tracuutuvi.com source interprets line 2 as having central and correct virtue, deserving to advance but lacking strong supporters, so it advances alone and feels dejected; if one keeps to virtue, better opportunities will come soon.

Luc tam: trusted by the crowd

Original: "眾允，悔亡"

Sino-Vietnamese: "Chung doan, hoi vong."

Meaning: the crowd trusts and follows; the heart is at ease.

This is the most comfortable stage of the hexagram in the common reading. Trust from those around is high, and no extra effort is needed to make an impression. The HOROS source calls this the stage where "whatever you do goes smoothly, whatever you say is heard."

Cuu tu: advancing like a big rat

Original: "晉如鼫鼠，貞厲"

Sino-Vietnamese: "Tan nhu thach thu, trinh le."

Meaning: advancing like a big rat; holding firm is also perilous.

This is the only yang line in the inner trigram, yet it is judged severely. The image of the "thach thu" (big rat, also read as field rat) symbolizes someone greedy, hoarding much without sharing, climbing by tricks rather than ability. The HOROS source calls this the harshest warning in hexagram Tan: if you hold a position of power and scheme for profit, or use connections to "run" ahead instead of using competence, the line speaks plainly. The tracuutuvi.com source interprets similarly: line 4 is neither correct nor central, sits high, is greedy to keep its seat, and thus easily meets danger.

Luc ngu: no worry over gain or loss

Original: "悔亡，失得勿恤，往吉，無不利"

Sino-Vietnamese: "Hoi vong, that dac vat tuat, vang cat, vo bat loi."

Meaning: the heart is at ease. Do not worry over gain or loss; advancing is good, nothing is unfavorable.

This is the ruling line of hexagram Tan in the common reading. The tracuutuvi.com source says line 5 rules hexagram Tan, possessing bright virtue because it sits at the center of the outer trigram Ly and is supported by the three yin lines below, so there is nothing to regret. Though line 5 is yin and yielding, success is not easy, but if one keeps bright virtue, success will come. The HOROS source interprets: one who can let go of small matters to focus on great ones can fully use the time of Tan.

Thuong cuu: advancing with horns

Original: "晉其角，維用伐邑，厲吉無咎，貞吝"

Sino-Vietnamese: "Tan ky giac, duy dung phat ap, le cat vo cuu, trinh lan."

Meaning: advancing with horns; only fit for subduing disorder at home. Perilous yet good, no fault, but holding firm is regrettable.

This is the highest line, a yang line at the top of the hexagram. The image of "horns" is something hard and sharp, used for butting. The HOROS source interprets: at this stage the energy of advancing should be used for one thing only, correcting faults at home and settling internal problems; taking the horns to butt outward will cause trouble. The tracuutuvi.com source also says this line only protects one's position and personal assets, not enough to build a great career. The phrase "phat ap" (attacking a city, subduing a town) carries ancient military meaning; this is the social context of the past and should not be read as advice for action.

Is hexagram Tan auspicious or inauspicious?

The common classification in Vietnamese I Ching sites places Tan among the auspicious hexagrams. The tracuutuvi.com source states clearly that Hoa Dia Tan is regarded as an AUSPICIOUS hexagram because it carries good meaning and favorable timing. The HOROS source also describes Hoa Dia Tan as a sign of favorable progress, when talent and effort begin to be seen and recognized.

Still, two layers must be distinguished: the Judgment and the Image speak of the general time, while the line texts speak of specific positions. Within the same hexagram Tan, line 4 is severely warned, and line 6 is noted as "trinh lan" (holding firm is regrettable). That means even in a hexagram classed as auspicious, there are line positions whose texts are not at all comfortable. This is what interpretive schools often stress: do not read the hexagram by its overall auspicious or inauspicious label, but by line and by the specific question.

How do schools of interpretation differ on hexagram Tan?

There are at least two different approaches to hexagram Tan in the tradition.

The first is reading by Confucian moral meaning, focusing on the Image text "tu chieu minh duc" (making one's own bright virtue shine). In this reading, Tan is a lesson in self-cultivation so that bright virtue radiates on its own, without seeking outside help. This reading is tied to the Great Learning tradition, which holds that "making bright virtue shine" is the starting point of self-cultivation.

The second is reading by hexagram image and line relations, emphasizing yin and yang positions and whether lines correspond or not. In this reading, lines 2 and 5 are both yin and so do not correspond in the sense of yin and yang seeking each other, which forces line 2 to advance alone. This reading is common in divination books following Mai Hoa Dich So and in folk interpretive tradition.

The two readings do not exclude each other but yield different emphases: one stresses morality, the other stresses stance and position. This article does not choose one as the sole standard but presents both for readers to compare.

Hexagram Tan in the Sequence and the lesson of a time of advancing

In the Sequence, Tan comes after Dai Trang (34) and before Minh Di (36). Dai Trang is the stance of great strength; Tan is the step that uses that stance; Minh Di is the time when light is wounded, the sun setting into the earth. Read as three consecutive hexagrams, a cycle appears: growing strong, advancing, then a time when light is obscured. This cyclical reading is used by many traditional I Ching books to explain why no time lasts forever.

The practical lessons that the sources all stress can be summed up in a few points. First, the time of Tan is a time of being seen, so what is needed is to make one's bright virtue truly bright, not to seek display. Second, the six lines show that in the same time of advancing, each position has a different approach: line 1 is patient, line 2 holds firm, line 3 uses trust, line 4 guards against greed, line 5 lets go of small matters, line 6 knows when to stop. Third, the greatest warning of the hexagram is not being blocked but advancing the wrong way: advancing through greed (line 4) or overreaching after reaching the top (line 6).

It should be said clearly that the I Ching is an ancient system of knowledge interpreted differently by many schools over thousands of years. Casting hexagram Tan is not proof of promotion, finances, or health. The sources referenced in this article all present the hexagram as a tool for reflection and orienting thought, not a verdict. Readers should use the hexagram as a mirror to review their own situation, not as a replacement for practical decisions.
