What Are the Ten Gods?
In Bát Tự (Four Pillars), a person's chart is built from eight characters: a stem and a branch for each of the Year, Month, Day, and Hour pillars. The Day Stem, called the Day Master, sits at the center of the chart, representing the person themselves. The Ten Gods (Thập Thần) are a system of ten labels used to describe the generating and controlling relationships between the Day Master and every other stem and branch in the chart.
Each relationship is determined by two factors: (1) how the element of that stem or branch relates to the Day Master's element within the Five Elements generating/controlling cycle (generates, is generated by, controls, is controlled by, or matches), and (2) whether that stem or branch shares the same yin-yang polarity as the Day Master (both yang or both yin) or the opposite polarity.
The Ten Stars
Same-element group (matches the Day Master):
- Tỷ Kiên (Companion): same element, same polarity as the Day Master. Represents siblings, friends, colleagues, independence, and fair competition.
- Kiếp Tài (Rob Wealth): same element, opposite polarity. Also represents siblings and friends, but with a competitive edge, often signaling wealth loss caused by others.
Group generated by the Day Master (Output):
- Thực Thần (Eating God): the element the Day Master generates, same polarity. Represents creativity, enjoyment, talent, children (for women), and a gentle temperament.
- Thương Quan (Hurting Officer): the element the Day Master generates, opposite polarity. Also relates to talent and creativity, but with a rebellious, unconventional streak prone to conflict with authority.
Group controlled by the Day Master (Wealth):
- Chính Tài (Direct Wealth): the element the Day Master controls, opposite polarity. Represents stable income, a wife (for men), diligence, and disciplined financial management.
- Thiên Tài (Indirect Wealth): the element the Day Master controls, same polarity. Represents windfall income, business opportunities, extramarital relationships (for men), generosity, and a taste for risk.
Group controlling the Day Master (Officer/Killings):
- Chính Quan (Direct Officer): the element that controls the Day Master, opposite polarity. Represents status, reputation, discipline, a husband (for women), and adherence to rules and law.
- Thất Sát (Seven Killings, also called Indirect Officer): the element that controls the Day Master, same polarity. Also relates to power, pressure, and challenge, but in a harsher, more competitive way, sometimes signaling adversaries or danger.
Group generating the Day Master (Resource/Seal):
- Chính Ấn (Direct Seal): the element that generates the Day Master, opposite polarity. Represents a mother figure, education, mentors and benefactors, legitimate reputation, and protection.
- Thiên Ấn (Indirect Seal, also called Kiêu Thần): the element that generates the Day Master, same polarity. Also relates to education and intellect, but leans toward independent or unconventional thinking, spirituality, and can sometimes bring isolation or block the Thực Thần star.
How the Ten Gods Are Used in Reading a Chart
The Ten Gods are never read in isolation, they must be considered within the full chart: which stars appear frequently, which are absent, and whether a star is supported or weakened by other pillars all shape a person's personality tendencies and life path. For example, someone with strong Chính Quan and Chính Ấn tends to suit structured, disciplined work such as government or corporate careers; someone with strong Thực Thần and Thương Quan often has artistic or creative talent suited to freelance or creative work; and someone with strong Chính Tài and Thiên Tài tends to have a sharp instinct for business.
Accurately interpreting the role of each Ten God star also depends on whether the Day Master itself is strong or weak (thân vượng or thân nhược), because the same star can be a favorable "useful god" (dụng thần) for one person and an unfavorable "unfavorable god" (kỵ thần) for another. For this reason, the Ten Gods should be treated as one foundational layer of information, to be combined with an overall assessment of the chart's Five Elements balance, rather than interpreted as the meaning of a single star in isolation.
