I Ching

I Ching Divination

Supports three casting methods: number casting (three numbers reduced by remainder), the Great Expansion yarrow method (enter line values directly), and time casting (the hexagram is determined automatically from the mystic number of the Four Pillars at the moment of inquiry).

Determine the hexagram by number remainders — simple and quick

Enter three integers (1–9999) to cast the hexagram. Leave the fields blank for a random cast. The upper number mod 8 determines the upper trigram, the lower number mod 8 determines the lower trigram, and the moving-line number mod 6 determines the changing line.

Preparation Before Casting

Before casting a hexagram, first settle your mind. I Ching divination emphasizes observing the timing and assessing the situation, rather than urgently seeking an absolute answer. The clearer your question, the more easily the resulting hexagram can be interpreted within a specific context; the calmer your mind, the less it will be disturbed by distracting thoughts.

Clarify Your Question

The more specific the question, the easier it is to interpret the hexagram. A query like 'How will my career be this year?' is too broad; changing it to 'Is it appropriate for me to change my career path at this moment?' makes it much easier to derive a clear judgment.

Quiet the Mind

Before casting, allow yourself to settle into quietude and focus your mind on the matter at hand. The more turbulent your emotions, the easier it is to project subjective biases onto the meaning of the hexagram.

One Question at a Time

It is best for each hexagram to address only one core question. Avoid mixing career, relationships, and wealth into a single query, as this will dilute the focus of the interpretation.

Avoid Repeated Inquiries

If there has been no new development in the situation, you should not cast a hexagram repeatedly for the same matter. Inquiring too frequently does not yield more information; rather, it only further disturbs the mind.

Record the Time and Question

We recommend keeping a record of the time of casting, the question asked, the primary hexagram, the changing lines, the transformed hexagram, and how the situation subsequently unfolded. Over time, this cumulative record will facilitate review and learning, making it easier to develop your own interpretive experience.

Methods of Casting the Hexagram

While there are many methods for casting a hexagram, the most important thing for beginners is to stick to a single method first. The specific method matters less than keeping clear, consistent records and avoiding the mixing of different guidelines.

Method 1: The Number Method

The numerical casting method is relatively simple. The common practice is to take a set of numbers and divide them by eight or six to derive the upper trigram, lower trigram, and the changing line. It requires no copper coins or yarrow stalks; any source of numbers will do—such as random numbers, timestamps, telephone numbers, page numbers, or house numbers. Its main advantage is speed and convenience, while its drawback is the abundance of different schools and varying rules. If beginners adopt this method, it is best to stick to one algorithm rather than mixing the rules of different teachers.

Method 2: The Great Expansion (Dayan) Method

The Dayan Method is the oldest form of yarrow stalk divination, recorded in the 'Great Treatise, Part I' (Xici Shang) of the I Ching. The original text states: 'The number of the Great Expansion is fifty, of which forty-nine are used. Divide them into two to represent the two primal forces; set one aside to represent the three powers; count them off by fours to represent the four seasons; and return the remainder to the fingers to represent the intercalary month.' Specifically, fifty yarrow stalks are gathered, with one set aside and unused. The remaining forty-nine stalks are divided at random into two heaps (representing the dual cosmic forces); one stalk is taken from the right heap and placed between the fingers (representing the three realms of Heaven, Earth, and Humanity); the stalks in each heap are then counted off in groups of four (representing the four seasons); the remainders are tucked between the fingers (representing the intercalary month). Three changes yield one line, and eighteen changes complete a hexagram. This method offers a profound sense of ritual and classical authenticity, making it ideal for those who wish to deeply understand the original divination techniques; conversely, the steps are intricate and require regular practice to master.

Method 3: The Three Coins Method

The three coins method is currently the most popular and accessible technique. Three identical coins are tossed six times consecutively, generating one line per toss to form a six-line hexagram. When recording the results, it is crucial to remember that hexagrams are drawn from the bottom up: the first toss determines the initial line (at the very bottom), and the sixth toss determines the top line.

Hexagram Interpretation Methods

Zhu Xi's Changing-Line Method from Yixue Qimeng (Site Default)

Six lines remain unchanged: Refer to the judgment of the primary hexagram.

One changing line: Refer to the line text of the changing line in the primary hexagram.

Two changing lines: Refer to the line texts of the two changing lines in the primary hexagram, with the upper line as the primary reference.

Three changing lines: Refer to the judgments of both the primary and transformed hexagrams, but still prioritize the primary hexagram.

Four changing lines: Refer to the line texts of the two unchanging lines in the transformed hexagram, with the lower line as the primary reference.

Five changing lines: Refer to the line text of the single unchanging line in the transformed hexagram.

Six changing lines: For Qian, take the Use of Nine text as primary; for Kun, take the Use of Six text as primary. For the other sixty-two hexagrams, take the relating hexagram judgment as primary.

Takashima Ekidan Interpretation Methods

No changing lines: Refer to the judgment in the original hexagram related to the query.

Only one changing line: Refer to the judgment corresponding to the changing line.

Two changing lines: Prioritize the original hexagram and refer to the transformed hexagram.

Three changing lines: Synthesize the original and transformed hexagrams, referencing both to reach a conclusion.

Four changing lines: Prioritize the transformed hexagram and refer to the primary hexagram.

Five changing lines: Prioritize the transformed hexagram and refer to the primary hexagram.

Six changing lines: Refer directly to the judgment in the transformed hexagram related to the query.

Cheng Jiong's Zhouyi Gufa (Additional Reference)

No changing lines: Read the primary hexagram judgment together with the inner and outer trigrams.

One changing line: Read that moving line in the primary hexagram.

Two to four changing lines: Read the primary hexagram as zhen and the relating hexagram as hui; do not force a single dominant line.

Five changing lines: Highlight the sole unchanging line and compare the corresponding texts in both hexagrams.

Six changing lines: For Qian and Kun, consult the Use of Nine and Use of Six; other hexagrams require a comprehensive judgment.

Nan Huai-jin's Moving-Line Method from Miscellaneous Talks on the I Ching (Additional Reference)

No changing lines: use the primary hexagram judgment; one changing line: use that moving line.

Two changing lines: if one is yin and one yang, emphasize the yin line; if they share the same polarity, emphasize the upper line.

Three changing lines: use the middle-positioned one of the three moving lines.

Four changing lines: use the lower of the two unchanging lines; five changing lines: use the sole unchanging line.

Six changing lines: Qian and Kun use the Use of Nine and Use of Six. Accounts for the other hexagrams vary, so this is included only as a reference.

Summary Table of I Ching Judgment Terms

The I Ching's judgment terms do not form a single scale from excellent to disastrous. Read overall tendency, conditions for action, risk, responsibility, and timing separately, then return them to the specific hexagram or line text.

I Ching Divination

I Ching Divination How To Use

What can this tool be used for?

I Ching divination is ideal for learning the relationships between the 64 hexagrams, changing lines, transformed hexagrams, and their classical texts. It digitizes the casting process, allowing users to quickly obtain hexagrams and refer back to classical texts for deeper meaning.

How do I use this tool?

You can choose from number casting, the Dayan yarrow stalk method, or time-based casting. After proposing a specific question and completing the cast, the system will display the original hexagram, changing lines, and transformed hexagram. We recommend asking one question at a time and not repeating casts for the same query.

How should I interpret the results?

First, read the original hexagram to understand your current situation, then study the changing lines to understand key transitions, and finally refer to the transformed hexagram to observe future trends. Traditional interpretations emphasize analyzing the context of your question rather than mechanically applying labels of good or bad fortune.

What scenarios is this suitable for?

It is suitable for beginners learning the I Ching, studying hexagram imagery, or performing comparative research with other divination systems. The results are intended solely for cultural study and entertainment, and do not constitute real-world decision-making advice.

FAQ

How many hexagrams are in the I Ching?

The I Ching consists of 64 hexagrams, each composed of six lines. This tool displays traditional texts including hexagram names, judgments, Tuan commentary, Xiang commentary, and changing line texts.

What is the difference between number casting and the Dayan method?

The Dayan method simulates the traditional yarrow stalk divination, with steps closer to ancient rituals, whereas number casting is simpler and more convenient for daily study. Both should be used under consistent rules.

What does a changing line mean?

A changing line (moving line) is a line that undergoes transformation. When its polarity flips, it forms the transformed hexagram corresponding to the original. The texts of changing lines are usually the key focus of interpretation.

Is drawing a negative hexagram always a bad sign?

No. Hexagrams serve more as indicators of current situations, potential risks, and action timing. Traditional interpretations must be integrated with the specific context of your question, rather than equating a hexagram name directly with real-world outcomes.

Can this tool replace professional advice?

No. This tool is designed for I Ching text study and folk divination reference, and does not constitute legal, medical, investment, psychological, or life-planning advice.
