Ask the coins
Three coins thrown six times give a hexagram, which is then read against the kind of matter being asked. The same hexagram answers a money question and a career question differently, because the governing line differs. The answer is therefore not in the hexagram's name but in what you were asking.
Cast three coins six times. The hexagram is fitted with stems, branches, the Six Relatives, Self and Other, and read through the god of use for the matter you are asking about.

What is Najia Six-Line divination, and how does it differ from plain I Ching casting?
Classical I Ching divination casts a hexagram and reads the line statements already written in the Zhou Yi. Six-Line divination, also called Najia, bushi, or King Wen hexagrams, adds a step: once the six lines exist, each line is FITTED with a heavenly stem and an earthly branch, from which come the line's element, and the generating and controlling relations among the lines and with the day of the cast. The reading is therefore derived on the spot rather than quoted, which is why the same hexagram cast today and next month gives different answers.
The method is attributed to Jing Fang (77–37 BCE) of the Han dynasty, who brought the stem-branch and five-element systems into Yi studies. It was completed across three works: the Song-era Huo Zhu Lin, and the Qing-era Bushi Zhengzong and Zengshan Buyi, the last, by the Wild Crane Elder, being the text most used by Vietnamese practitioners.
The sixty-four hexagrams are sorted into EIGHT PALACES of eight, headed by the eight doubled trigrams. The order within a palace is not arbitrary but generated by flipping lines: from the doubled hexagram, flip line 1 for the First Generation, then line 2 for the Second, and so on to the Fifth; the seventh flips line 4 BACK, called the Wandering Soul; the eighth restores the whole inner trigram, called the Returning Soul. This tool derives the palace table by that rule rather than transcribing it, then checks the result against Jing Fang's published table, all fifty-six mixed hexagrams matched on the first run.
The PALACE's element acts as "self", and the six lines are named by their relation to it, the Six Relatives. What generates self is Parent, what self generates is Offspring, what self controls is Wife-Wealth, what controls self is Officer-Ghost, and same-element is Sibling. This is how Six-Line divination answers a specific question: money is read at Wife-Wealth, career and examinations at Officer-Ghost, documents and contracts at Parent, children and peace of mind at Offspring. The line singled out is the GOD OF USE. Choose it wrongly and the whole reading follows it wrongly, so this tool asks what you are asking about before you cast, not after.
The SELF line is where the querent stands; the OTHER line is the far side, the counterparty, the other person, the circumstance. The Self line's position follows from the hexagram's rank in its palace, and Other always sits three lines away. Their generating-controlling relation shows which way the situation leans; Self controlling Other is a different matter from Other controlling Self, even with the same two parties.
The VOID is a separate idea, often misread. The sixty stem-branch pairs fall into six ten-day cycles; with ten stems against twelve branches, two branches in every cycle have no stem to pair with, those two are that cycle's void. A line whose branch falls in the void is not yet arrived, not yet formed, it does NOT mean ruined. A void line that is otherwise strong is called "void but not empty", and the matter moves on the day that clashes the void.
A HIDDEN GOD arises when the cast hexagram contains no line carrying the relative you need. The god of use is then hidden beneath a line of the palace's parent hexagram, and the line on the surface is called the flying god. The matter can still be read, but the reading must say plainly that it is obscured and needs a new condition to surface, rather than quietly reading the surface line and calling it done.
Two kinds of question this tool DELIBERATELY does not take: finding missing persons, and illness. The classical texts have chapters on both, but a wrong answer here is not merely a wrong answer, it stops people searching, or stops them seeing a doctor. Not a technical limit, a choice.
The cast is RANDOM. Three coins six times gives 4,096 combinations, and there is no scientific basis for a link between that outcome and the matter you asked about. The real value lies in being made to state your question clearly, then given another angle to hold it against. Serious matters need real information and qualified people.
| Relative | Relation to palace element | Read as god of use when asking about |
|---|---|---|
| Parent | Generates self | Documents, contracts, property, vehicles, study, news, parents |
| Sibling | Same element as self | Siblings, friends, rivals competing for the same thing, money split or lost |
| Offspring | Generated by self | Children, subordinates, peace of mind, relief from trouble, physicians |
| Wife-Wealth | Controlled by self | Money, income, assets, a wife or partner (for a male querent) |
| Officer-Ghost | Controls self | Career, examinations, superiors, litigation, a husband (for a female querent) |
| Self / Other | Outside the Six Relatives | Self is where you stand, Other is the far side |
Frequently asked questions
Is Ask the Coins free to use?
Completely free, with no cap on casts and no login required. Casts are not stored on the server either.
How does Six-Line divination differ from plain I Ching casting?
Plain I Ching reads the line statements as written in the classic. Six-Line divination fits stems and branches to each line, then derives elements, the Six Relatives, Self and Other, and the relation to the day of the cast, so the reading is derived on the spot and changes with both the day and the matter asked.
What is the god of use, and why pick the matter before casting?
The god of use is the line standing for the matter itself, money at Wife-Wealth, career at Officer-Ghost, documents at Parent. The same hexagram read for a different matter means reading a different line, so the matter comes first; a wrongly chosen god of use makes the whole reading wrong.
Is a line falling in the void a bad sign?
No. The void means not yet arrived, not yet formed. Every ten-day cycle leaves two branches with no stem to pair with, and those are its void. A void line that is otherwise strong is "void but not empty", and the matter moves on the day that clashes the void.
Why can't I ask about illness or a missing person?
The classical texts do cover both, but a wrong answer here does not merely miss, it stops people searching, or stops them seeing a doctor. This is a deliberate choice, not a technical limit.
What if the hexagram has no line for what I need?
That is the hidden god case: the god of use lies beneath a line of the palace's parent hexagram, with a flying god on the surface. The tool still reads it, and says plainly that the matter is obscured and needs a new condition to surface.
Can I recast the same question many times?
Technically yes, but the tradition holds that asking the same thing repeatedly shows no sincerity and voids the later casts. More practically: casting until you get the answer you wanted means the cast tells you nothing.
Should I use the result to decide something important?
No. The cast is random and there is no scientific basis linking it to your situation. Its value is in making you state the question clearly and offering another angle to check against; serious matters need real information and qualified people.
