What is the Tu Ton line in the Luc Than system?
In Luc Hao, each hexagram is assigned six lines with six relationships called Luc Than: Phu Mau, Huynh De, The Tai, Tu Ton, Quan Quy, and the querent themselves (the The line). The rule for assigning Luc Than is based on the element of the palace trigram: taking the palace element as the standard, the line that generates the palace element is Phu Mau, the line sharing the palace element is Huynh De, the line generated by the palace element is Tu Ton, the line the palace controls is The Tai, and the line that controls the palace is Quan Quy. Thus Tu Ton is the line whose element is generated by the palace element, that is, "what I generate."
The book Luc Nham, volume 1, introductory section, defines it briefly: Tu Ton is children and grandchildren. To know the fortune of children, find the Tu Ton line and judge from it. Beyond children, this line also extends to students, subordinates, livestock, and monastics, meaning those people or creatures in the layer of "being nurtured, commanded, and guided" by the querent.
Because it is the line generated by the palace, Tu Ton also carries the meaning of the self's "escaping energy." The Luc Nham book states clearly: when asking about livelihood and business, encountering Tu Ton is not good, because Tu Ton drains the energy of the Can, that is, the self, since the Can inherently generates Tu Ton and therefore must be depleted. Hence Tu Ton is also called the Escaping Energy line. This is a point easily overlooked when beginners only remember the phrase "Tu Ton is a blessing spirit."
Why is Tu Ton called a blessing spirit?
Tu Ton controls Quan Quy, and Quan Quy in Luc Hao is the line symbolizing disaster, illness, lawsuits, punishments, and those who oppress you. When Tu Ton can control Quan Quy, disaster is stopped, so Tu Ton is called the saving spirit, the line of blessing and virtue. Volume 1 of the Luc Nham book affirms: the Tu Ton line is what is needed when divining harmful matters such as illness or legal trouble, because the line causing disaster is the Quan Quy line and is controlled by the Tu Ton line; for this reason the Tu Ton line bears the names saving spirit and blessing line.
Also according to the Luc Nham book, the Tu Ton line is very favorable when meeting the Huynh De line, because Huynh De generates Tu Ton, but very taboo when meeting the Phu Mau line, because Phu Mau controls Tu Ton. When divining for wealth, the The Tai line likes to meet the Tu Ton line because Tu Ton is precisely the source that generates The Tai. These three relationships, Tu Ton generates Tai, Tu Ton controls Quy, and Phu Mau controls Tu Ton, are the backbone for understanding all judgments about the Tu Ton line.
What does Tu Ton holding the World line indicate?
The old verse "Tu hao tri the su vo uu" means that when the Tu Ton line holds the World line, all matters are free from worry and sorrow. The verse for divining hexagrams continues: "Cau danh thiet ky toa duong dau," meaning when seeking fame, it is highly taboo for Tu Ton to hold the World line or for Tu Ton to become active and control the Quan line. The same verse adds: "Ty loan hua an that kha dac, quan tung tung kim tien lieu huu," meaning fleeing chaos will surely be safe, no need to worry about loss or damage, and legal matters will likely be settled.
Thus, within a single line holding the World, the meaning splits in two according to the question. If asking about personal safety, lawsuits, or calamity, then Tu Ton holding the World is a clear auspicious sign. If asking about exams, promotion, or seeking office, then Tu Ton holding the World nearly blocks the path, because it controls away the Quan Quy line, the line representing career and rank.
The book Tang San Boc Dich by Da Hac lao nhan, in the section Seeking Official Career, writes plainly: if encountering Tu Ton holding the World, or Tu Ton active in the hexagram, then seeking to pass exams or seeking promotion is like scooping the moon from the bottom of the water. In the same book, in the section Divining Fortune and Misfortune, it again places Tu Ton holding the World in the group of inauspicious signs for one currently holding official position, but for an ordinary person divining a month's fortune, it is joyful to get the Tai or Tu Ton line holding the World, promising a year of smooth progress. This is a typical example showing that the same line, in the same position holding the World, yields a completely reversed conclusion when the querent changes.
When is Tu Ton the useful spirit?
The useful spirit is the line representing the matter being asked about. When the question falls precisely within the scope of Tu Ton, this line becomes the useful spirit and all judgments revolve around it. Common cases include: asking about children, asking about students, asking about subordinates or employees, asking about livestock, and asking about resolving disaster, seeking peace, and escaping danger.
According to the Luc Nham book's guidance for questions about children: if the Tu Ton line is in a prosperous and strong state and carries auspicious signs and auspicious spirits, then the children are fortunate; conversely, if it falls into a resting, imprisoned, or dead state and carries inauspicious signs and inauspicious spirits, then the children meet harm. This method of judgment applies both to asking about children already born and to asking about having children.
When Tu Ton is the useful spirit, the Phu Mau line becomes the taboo spirit because it controls Tu Ton, while the Huynh De line becomes the original spirit because it generates Tu Ton. This is why, in the same hexagram, one asking about career and one asking about children will read two opposite conclusions from the same generating and controlling structure.
Tu Ton active and generating The Tai when asking about money
The book Tang San Boc Dich, in the section Divining for Wealth, lists cases that promise wealth: the Tai star holding the World; or the day, month, or active line being Tu Ton and generating and combining with the World line; or Quan Quy holding the World and being generated by an active Tai. Conversely, if encountering Huynh De holding the World, or the Huynh De line active in the hexagram, or the World falling into Empty Cycle or Monthly Destruction, then it is no different from climbing a tree to catch fish.
The notable point is that Tu Ton is not directly money; it is the source that generates money. The Tai is the line of money and wife. Tu Ton active and generating The Tai means there is a source of strength, a person, or a matter creating a stream of money, not that one is holding money oneself. Therefore when asking for wealth and seeing Tu Ton active and generating Tai, that is a good signal about income sources, especially when the World line also receives that generating stream.
The Luc Nham book also confirms: when divining for wealth, the The Tai line likes to meet the Tu Ton line, because Tu Ton generates The Tai. However, one must distinguish this from the case of asking about livelihood and business in general, where Tu Ton is instead the Escaping Energy line, depleting the self, and thus not good. The two questions "seeking wealth" and "livelihood" sound close but the conclusions about Tu Ton differ, and this is where many learners often confuse them.
Why is the same line both a blessing and an obstacle?
The answer lies in the fact that Tu Ton has only one fixed behavior: it generates The Tai and controls Quan Quy. Auspicious or inauspicious does not lie in the line itself, but in which line is currently the useful spirit.
If Quan Quy is the useful spirit, meaning asking about career, rank, exams, or lawsuits where one is the defendant, then Tu Ton controls the useful spirit, becoming the taboo spirit, and the result is unfavorable. If Quan Quy is the enemy spirit, meaning asking about disaster, illness, or an oppressor, then Tu Ton controls the enemy spirit, becoming the joyful spirit, and the result is good. If The Tai is the useful spirit, meaning asking about money, then Tu Ton generates the useful spirit, becoming the original spirit, and the result is favorable.
The three roles of taboo spirit, joyful spirit, and original spirit of the same Tu Ton line, depending on the question:
| Question | Useful spirit | Role of Tu Ton | General conclusion |
|---|---|---|---|
| Seeking office, exams, promotion | Quan Quy | Taboo spirit (controls useful spirit) | Unfavorable, highly taboo for Tu Ton to hold the World or be active |
| Seeking wealth, trade | The Tai | Original spirit (generates useful spirit) | Favorable, especially Tu Ton active and generating Tai |
| Resolving disaster, seeking peace, lawsuits | Quan Quy as enemy spirit | Joyful spirit (controls enemy spirit) | Good, bad news dissolves, danger turns to safety |
| Asking about children, students, livestock | Tu Ton | Useful spirit | Depends on the strength or weakness of the Tu Ton line itself |
| Asking about livelihood and business in general | The self (Can) | Escaping Energy line (depletes the self) | Not good |
This table is built from the core calculation: Tu Ton is the line generated by the palace element, so it always generates the line the palace controls (The Tai) and always controls the line that controls the palace (Quan Quy). All auspicious and inauspicious conclusions are derived from these two fixed relationships plus determining the useful spirit.
Table for finding the Tu Ton line by the eight palaces
Each palace trigram has one element, and the Tu Ton line is the line carrying the element that the palace element generates. Below is a table by the eight palaces, with the branches carrying the corresponding element in the na jia system. The column "branches carrying that element" lists the Earthly Branches with that element, used for quick cross-checking when reading a hexagram.
| Palace | Palace element | Element of Tu Ton | Branches carrying that element |
|---|---|---|---|
| Can | Metal | Water | Ty, Hoi |
| Doai | Metal | Water | Ty, Hoi |
| Ly | Fire | Earth | Thin, Tuat, Suu, Mui |
| Chan | Wood | Fire | Ty, Ngo |
| Ton | Wood | Fire | Ty, Ngo |
| Kham | Water | Wood | Dan, Mao |
| Can | Earth | Metal | Than, Dau |
| Khon | Earth | Metal | Than, Dau |
How to use the table: when you know which palace the hexagram belongs to, look up the element of Tu Ton, then find among the six lines of the hexagram which line carries that element; that line is Tu Ton. For example, a hexagram belonging to the Kham palace has Tu Ton as the Wood line, meaning lines carrying the branches Dan or Mao. A hexagram belonging to the Can or Doai palace has Tu Ton as the Water line, meaning lines carrying the branches Ty or Hoi.
One easily confused point should be noted: the element of Tu Ton is derived from the palace element, not from the element of the querent themselves. Therefore the same branch line in two hexagrams of different palaces can carry different Luc Than. This is also why one must establish the hexagram correctly according to the na jia rules before judging, and cannot guess by feeling.
Where schools and books disagree
The biggest difference lies in how Tu Ton is evaluated. The book Tang Bo Boc Phe Chinh Tong by Vuong Duy Duc (courtesy name Hong Tu) has a transmitted phrase: nobles take Tu Ton as an evil star, commoners take Tu Ton as a blessing spirit. That means for one currently holding rank, currently within the official system, Tu Ton is a bad star because it destroys career; while for ordinary people, Tu Ton is a lucky star because it resolves disaster and removes harm. This view matches how Tang San Boc Dich distinguishes those currently in office from ordinary people when divining fortune and misfortune.
Another point to state clearly: many books assign Tu Ton to medicines and to healing, regarding Tu Ton as the line of physicians and prescriptions. This assignment does exist in tradition, but this article only records it as a convention of some books and does not use it to give medical advice. Asking about illness and judging illness by Luc Hao is a separate field, outside the scope of this article, and one should not extrapolate from a few verses to apply to health.
There is also disagreement about whether Tu Ton is regarded as the line of monastics and practitioners. Some books place monastics under Tu Ton because Tu Ton is the "world-escaping" line, free from the cycle of rank. Other books place them under Phu Mau or Quan Quy depending on the case. This article follows the more common placement in widely used Luc Hao books, placing monastics under Tu Ton, and states clearly that this is a convention, not a mandatory rule for all schools.
A few notes when judging the Tu Ton line
First, never conclude auspicious or inauspicious from the line's name alone. Determine the useful spirit first, then examine what role Tu Ton is playing. With the same Tu Ton holding the World, one asking about lawsuits and one asking about exams receive two opposite answers.
Second, whether Tu Ton is prosperous and strong or resting and imprisoned only indicates the line's degree of strength or weakness; it does not by itself change the sign of auspiciousness or inauspiciousness. A strong Tu Ton that is currently the taboo spirit becomes more unfavorable for career the stronger it is. A resting Tu Ton that is currently the joyful spirit resolving disaster can still be sufficient if supported by the Day and Month.
Third, relationships with Phu Mau and Huynh De must be read at the same time. Phu Mau controls Tu Ton, so when Phu Mau is strongly active, Tu Ton is restrained and all matters related to children and disaster resolution meet obstacles. Huynh De generates Tu Ton, so when Huynh De is active, Tu Ton is reinforced, but at the same time Huynh De is the line that drains wealth, so benefit and harm come together.
Fourth, concepts such as Empty Cycle, Monthly Destruction, active change, and advancing or retreating transformation all apply to Tu Ton as to any other line. A Tu Ton line active and transforming into Tu Ton is usually read as a layered image, many layers of children or a prolonged matter, but the specific reading still depends on the question and the book. One should not apply a rigid formula to every case.
A final methodological point: the conclusions above are valid only within the framework of the Luc Hao system with na jia and Luc Than rules. They are not predictions of the future in a certain sense, but a way of reading a rule-governed symbol system. Learners should regard this as a tool for reflection and contemplation, not a basis for decisions in place of their own reason and responsibility.
FAQ
What is the Tu Ton line and how is it determined in a Luc Hao hexagram?
The Tu Ton line is the line whose element is generated by the palace element of the hexagram, representing children, students, subordinates, livestock, and monastics. To determine it, first identify the palace the hexagram belongs to, then find the element that the palace element generates; the line carrying that element among the six lines is Tu Ton. For example, Kham palace is Water, so Tu Ton is Wood, meaning lines with branches Dan or Mao.
Why is Tu Ton called a blessing spirit yet taboo when asking about career?
Tu Ton is called a blessing spirit because it controls Quan Quy, the line of disaster, illness, lawsuits, and oppression, so it resolves sorrow and removes harm. But when asking about career, exams, or rank, Quan Quy is the useful spirit, so Tu Ton becomes the taboo spirit that controls away the very line representing success, making it highly unfavorable. The same behavior yields opposite results depending on which line is the useful spirit.
What does Tu Ton active and generating The Tai mean when asking about money?
Tu Ton is not money itself but the source that generates money, while The Tai is the line of money and wife. Tu Ton active and generating The Tai means there is a source of strength, a person, or a matter creating a stream of income, not that one is directly holding money. It is a good signal about income sources, especially when the World line also receives that generating stream.
