The I Ching Hexagram Meanings catalogue takes three ordered actions — search, filter, inspect — over a fixed 64-row Unicode table, and planning your steps means deciding which input to type, whether the lower or upper trigram filters narrow the result, and how to interpret the six-line structure you receive back. The catalogue is a reference, not a divination, so planning is really about reaching one specific entry quickly and reading it accurately. Every row pairs a King Wen number from 1 through 64 with one encoded character from U+4DC0 through U+4DFF, and the first entry is ䷀ at U+4DC0, named HEXAGRAM FOR THE CREATIVE HEAVEN by Unicode, while the last is ䷿ at U+4DFF, named HEXAGRAM FOR BEFORE COMPLETION. Because the table is fixed and small, planning means matching what you already know to one of the five search input types, then applying zero, one, or two trigram filters, then opening the chosen entry to verify its encoding and its split into a lower trigram (Lines 1 through 3) and an upper trigram (Lines 4 through 6).
Setting Up a Lookup Plan
Planning, in the context of the I Ching Hexagram Meanings tool, is the act of ordering your actions so that you move from a piece of information you already hold to the correct 64-entry row in the catalogue with as little wandering as possible. The catalogue is not a casting method and it does not generate predictions, so the only thing to plan is a lookup path.
Three concrete reasons a written plan helps:
- The 64 hexagrams look similar at a glance, and without a plan you can lose ten or more entries before finding the one you wanted.
- Each hexagram has five searchable identities: its King Wen number, its visible character, its Unicode code point, its official English name, and the trigram names that compose it. A plan picks the right one.
- Trigram filters narrow quickly, so knowing whether you want to constrain the lower trigram, the upper trigram, or both decides the rest of the session.
The catalogue is browser-based, the 64-row table is fixed, and no fetch request is made when you search or filter. That privacy floor lets you plan freely without worrying about clearing a history later.
The Five Inputs You Can Plan to Search For
Every plan starts by choosing the input type that matches what you already hold. The I Ching Hexagram Meanings tool accepts five distinct kinds of input in its search field, and you do not switch modes between them.
| Input Type | Example | Plan It For |
|---|---|---|
| King Wen number | 1 through 64 | When you know the traditional sequence position |
| Hexagram character | ䷀, ䷁, ䷿ | When you have the visible symbol from another source |
| Unicode code point | U+4DC0, U+4DFF | When you are verifying an encoding |
| Official Unicode name | HEXAGRAM FOR THE CREATIVE HEAVEN | When you have a Unicode NamesList label |
| Trigram term | Qian, Kun, Li, Zhen | When you want to find all hexagrams sharing a trigram |
A good plan checks which of these five you already hold before touching the search field. Entering a King Wen number such as 1 returns the first row of the catalogue, and entering the official name HEXAGRAM FOR THE CREATIVE HEAVEN returns the same row by a different path. Either route is valid, and the tool does not store your choice.
Run a Planned Lookup Session
Use this sequence whenever you sit down with the catalogue. Three short steps cover every planned lookup, and a fourth resets the tool when you finish.
- Identify which of the five input types you already have. If you have a King Wen number, type it. If you have a visible hexagram character, paste it. If you have a Unicode code point, an official name, or a trigram term, type that instead. The search field accepts any of these without switching modes.
- Read the result count. The catalogue announces how many entries match the current query. If the count is 1, proceed directly to inspection. If the count is higher than 1 and you know the structural composition, apply a trigram filter next.
- Apply the lower trigram filter for Lines 1 through 3 and/or the upper trigram filter for Lines 4 through 6 only when you need to. Picking one filter is often sufficient; picking both narrows the result to a single hexagram whose six lines split exactly at Line 3 into the chosen pair.
- Open the matching entry. The selected row shows its exact Unicode identity (the character, code point, and official Unicode English name) alongside its lower and upper trigram structure so the decomposition can be checked visually.
- Reset when you are done, or when you want to switch tasks. Reset catalogue clears the search field, removes both trigram filters, restores all 64 entries, and returns the tool to Hexagram 1.
This sequence never requires an account, never uploads the input, and never persists the filter state after the page is closed or refreshed.
Reading Lower and Upper Trigrams in the Selected Entry
Once a hexagram row is open, the plan turns to structure. A hexagram is six lines read from the bottom upward. The bottom three lines form the lower trigram, and the top three lines form the upper trigram. The eight trigrams the catalogue recognises appear in the filters and beside the selected entry with both their names and their symbols.
- Qian — Heaven
- Dui — Lake
- Li — Fire
- Zhen — Thunder
- Xun — Wind
- Kan — Water
- Gen — Mountain
- Kun — Earth
The lower and upper trigram codes are sourced from the Stanford Encyclopedia of Philosophy Yijing appendix, which publishes bottom-to-top yin and yang line codes for all eight trigrams and all 64 hexagrams. Splitting each six-line code after the third line gives the lower and upper trigrams the catalogue displays. The 8-by-8 King Wen lookup matrix is not inferred from the English title; it is independently locked against that appendix. This is a reference layer, not an interpretive one. The catalogue shows the structure; it does not generate a divination reading or change a line. If your plan needs a mechanical three-coin cast, the separate I Ching Reading tool covers that workflow, while this catalogue stays in lookup mode.
When to Reset the Catalogue
Reset is the closing step of any planned session. Three situations call for it:
- You have finished your lookup and want a clean slate before starting a second one.
- Your filter combination has produced an empty result and you want to recover quickly without reloading the page.
- You want to confirm that Hexagram 1 still sits at the head of the catalogue before handing the screen to someone else.
Reset catalogue performs four actions in order: it clears the search field, it clears both trigram filters, it restores all 64 entries, and it selects Hexagram 1 (䷀ at U+4DC0, HEXAGRAM FOR THE CREATIVE HEAVEN). Closing or refreshing the page also removes the transient filter state, so a reset is not strictly required when you are done. Privacy stays intact across resets: no fetch request is made, no query is uploaded, no localStorage or sessionStorage is written, and no account is required.
Treating the Catalogue as Reference, Not a Reading
A sound plan keeps the catalogue in its lane. The I Ching Hexagram Meanings tool is built around the received King Wen sequence, the Unicode Yijing Hexagram Symbols block (U+4DC0 through U+4DFF), and the Stanford Encyclopedia of Philosophy line-code appendix. It does not toss coins, choose a random entry, calculate changing lines, reproduce a modern commercial translation, attach an unsourced fortune, or claim that a hexagram predicts an event.
If your plan moves into divination, switch to a casting tool rather than stretching the catalogue. The catalogue will give you the exact encoding and structure for any of the 64 entries; the casting belongs elsewhere. Holding this boundary keeps every step of your plan repeatable and source-backed, which is the only definition of correctness the tool itself uses.
