Interpretive systems

Plum Blossom Numerology

No coins, no stalks, nothing to carry. A number taken from the hour, a count of objects, the sound of a bird, and a hexagram is built out of whatever is already happening. Then the reading proceeds by looking at what the two trigrams do to each other.

How a reading is built

Two stages: get a hexagram out of the situation, then read it through the images rather than the text. Both are quick, and the second is where the skill lies.

🕰️

Building from a time

China Song onward

Convert the year, month and day into numbers and divide by eight for the lower trigram; add the hour and divide by eight again for the upper; divide the whole by six for the moving line. The commonest way to get a figure from nothing.

🔢

Building from a count

China Song onward

Any number to hand will serve: the strokes in a written character, objects on a table, people in a room, a page number. Two numbers give the trigrams and their sum gives the moving line.

🐦

Building from what happens

China Song onward

A bird calling from the south, a broken vessel, a colour, a direction someone arrives from. The event is converted through the trigram correspondences, which is the method at its most characteristic and least reproducible.

🧑‍🤝‍🧑

Host and guest

China Song onward

The trigram containing the moving line is the guest, the other is the host standing for the querent. Nearly the whole judgement rests on this division, which has no counterpart in the classical reading.

🔄

Generating and controlling

China Song onward

Each trigram carries a Five Phase agent. If the guest generates the host the outcome is favourable; if it controls the host, unfavourable. The relation between the two is the verdict in one step.

🖼️

Reading the images

China Song onward

Metal cutting wood, fire drying a lake, wind entering a mountain. The reading is pictorial and situational rather than textual, which is why the eight trigram correspondences must be known cold.

🫀

The nuclear hexagram

China Song onward

Lines two to five give an inner figure read as the middle of the matter, between the situation as it stands and where it is going. Plum Blossom uses it far more heavily than the classical reading does.

➡️

The changed hexagram

China Song onward

Flipping the single moving line gives the outcome figure. Plum Blossom almost always works with exactly one moving line, which keeps the reading sharp and unambiguous.

👀

Corroborating signs

China Song onward

The diviner watches what happens during the consultation and treats it as part of the answer. A practice that makes the method vivid and makes it very hard to assess.

⚡

Speed as a principle

China Song onward

A reading takes a minute or two. The tradition treats the immediacy as substantive: the answer belongs to the moment it was asked in, and deliberation is held to spoil rather than improve it.

☝️

One question, once

China Song onward

Because the figure comes from the moment rather than from a randomiser, re-asking makes little sense; the moment has moved. The discipline is stricter here than in coin practice.

📕

Text as a secondary source

China Song onward

The Judgment and line texts may be consulted for colour, and the verdict comes from the trigram relation. Like Wen Wang Gua, this is a system that uses the figures more than the book.

Sources, ideas and cautions

The tradition's founder, the text that carries his name, and the things practitioners argue about.

Shao Yong

1011–1077 Luoyang

The Song cosmologist to whom the method is attributed, author of the Before Heaven arrangement and a cyclical chronology of the universe. Whether he devised this technique is uncertain; his name is what carries it.

The Meihua Yishu

attributed to Shao Yong, compiled later China

The manual that transmits the method, almost certainly assembled after Shao Yong's lifetime. It gives the numerical procedures, the trigram correspondences and a set of worked cases.

The plum blossom story

traditional China

Shao Yong is said to have watched two sparrows fight and fall from a plum tree, cast from the moment, and predicted that a girl would injure herself picking flowers there the next evening. The tale gives the method its name.

The Before Heaven numbers

11th century China

Shao Yong's arrangement numbers the trigrams one to eight, and those numbers are what the divisions in this method produce. The technique is downstream of his cosmology.

The trigram correspondences

Han onward China

Each trigram's image, phase, direction, season, body part, animal and family role. Plum Blossom depends on these more directly than any other method, since they are what the reading is made of.

Generation and control

Warring States onward China

Wood feeds Fire, Fire makes Earth, Earth bears Metal, Metal carries Water, Water grows Wood; and the controlling cycle that cuts across it. Two short sequences that decide most Plum Blossom verdicts.

Xin Yi, the heart method

Song onward China

A name for the intuitive side of the practice, where the diviner reads the situation directly through the images. Its defenders call it the method's essence; its critics call it where the discipline dissolves.

Against Six Lines

Song onward China

Wen Wang Gua computes from branches and phases attached to lines; Plum Blossom compares two trigrams and stops. One is bookkeeping, the other is pattern recognition, and many diviners use both.

Current practice

contemporary China, Taiwan, the diaspora

Widely taught alongside Six Lines and popular precisely because it needs no equipment. Frequently used for quick everyday questions where setting up a full cast would be disproportionate.

The reproducibility problem

perennial everywhere

Two practitioners given the same moment can derive different hexagrams, since what counts as the relevant number or event is a judgement. The tradition treats this as sensitivity; a sceptic will call it something else.

In English

1990s onward the West

Translations of the Meihua Yishu and modern manuals exist, and the method has a following among Western practitioners who want something faster and more visual than the classical reading.

Where to start

contemporary worldwide

Learn the eight trigrams and their correspondences thoroughly, then the two Five Phase cycles, then the host-and-guest rule. That is enough to begin; the rest is accumulated by reading cases.

Divination with empty hands

Every other method needs equipment. Yarrow needs fifty stalks and an hour, coins need coins, Six Lines needs both and a table of correspondences. Plum Blossom Numerology needs nothing at all, because it builds the hexagram out of the situation you are already standing in.

The commonest procedure uses the time. Convert the year, month and day to numbers, add them, divide by eight and take the remainder as the lower trigram. Add the hour, divide by eight again for the upper trigram. Divide the total by six and the remainder gives the moving line. You now have a hexagram and you have touched nothing.

Any other number will do just as well: objects on a table, people in a room, the stroke count of a written character, a page number, a licence plate. And in its most characteristic form the method takes the number from an event, a bird calling from a particular direction, a cup breaking, a colour noticed at the moment the question arose.

Reading by images, not by text

Having built the figure, the practitioner does not turn to the Judgment. Plum Blossom reads the two trigrams as pictures and asks what they are doing to each other.

The trigram containing the moving line is the guest, and the other is the host, representing the querent. Each carries a Five Phase agent. If the guest trigram generates the host, the answer is favourable; if it controls the host, unfavourable. That single relation carries most of the verdict, and it is why the eight correspondences have to be known cold.

Then the images fill in the detail. Metal over wood is cutting. Fire over a lake is drying up. Wind entering a mountain is slow penetration into something immovable. The reading is pictorial and situational rather than textual, closer to interpreting a photograph than to construing a sentence.

The nuclear hexagram, from lines two to five, is read as the middle of the matter, and flipping the moving line gives the outcome. Plum Blossom leans on both far more than the classical reading does, and it almost always works with exactly one moving line, which keeps the analysis sharp.

The sparrows and the plum tree

The name comes from a story. Shao Yong is said to have been watching plum blossom when two sparrows fought over a branch and fell to the ground. He took the moment as an omen, cast from it, and concluded that the following evening a girl would come to pick flowers, be startled, fall and injure her thigh. She did.

The story is doing a job: it demonstrates that the trigger can be any event, that the reading concerns something apparently unrelated to it, and that the method is fast. Whether Shao Yong devised the technique is uncertain, and the manual bearing his name was compiled after his lifetime. What is certain is that the numbers the procedure produces are the trigram numbers of his Before Heaven arrangement, so the method is genuinely downstream of his cosmology.

What is gained and what is risked

The gain is immediacy and range. A reading takes a minute, needs no equipment, and can be done anywhere. Practitioners use it constantly for small questions where setting up a formal cast would be absurd. The tradition also holds that the speed is substantive rather than merely convenient: the answer belongs to the moment the question arose in, and deliberating over the setup spoils the correspondence rather than improving it.

The risk is the obvious one. Because the practitioner chooses which number or event is the relevant one, two competent readers given the same moment can derive different hexagrams. The tradition reads this as responsiveness to the diviner's attention. A sceptic will read it as the method having no fixed input at all, and this is a fair description of the difficulty rather than an unfair one.

The strictest form, sometimes called the heart method, drops the arithmetic and reads the situation directly through the trigram images. Its defenders regard this as the tradition's essence, and it is also the point at which the method stops being checkable in any sense.

Where it sits

Plum Blossom and Wen Wang Gua are the two major indigenous Chinese systems for using the hexagrams, and they are near-opposites. Six Lines is technical, slow to learn, heavy with tables, and built for concrete questions with checkable outcomes. Plum Blossom is quick, visual, light on apparatus, and built for reading a situation as a whole.

Many practitioners know both and choose by question. The one thing they share is that neither treats the classic text as the source of the answer.
