ABOUT YIPHASE · SOURCES & METHOD
Learn the pattern.
Keep sight of the source.
YiPhase is a place to learn and share the I Ching, created by Jackie Yuen. We welcome curious beginners: start with a free Mei Hua Yi Shu reading, then explore the same cast through the I Ching’s hexagram, changing line and developing pattern. The initial reading and Deep Reading preview are both free during this feedback phase.
Classical text and modern explanation
The I Ching, or Book of Changes, is our textual foundation. Individual hexagram pages distinguish the Chinese judgment, line texts and commentaries from YiPhase’s English explanations and everyday examples. Our English text is an original learning interpretation, not a reproduction of a named translator’s complete edition. Different editions and translators can make different choices; compare the cited passage when a wording matters.
- Chinese Text Project · Book of Changes: a reference for the Chinese text. Each hexagram page also links its relevant Wikisource text.
- Mei Hua Yi Shu · volume one: number and calendar casting conventions and trigram relationships.
- Mei Hua Yi Shu · volume two, human affairs: the general body/use judgments of support, harmony, expenditure and constraint.
- Shuogua · Discussion of the Trigrams: classical trigram associations. Our room-observation exercises and journal prompts are modern applications, not a traditional property assessment.
How a reading is formed
Mei Hua with two numbers: the first number selects the upper trigram and the second the lower, using remainders modulo eight. Their sum selects the changing line modulo six. Remainder zero means eight or six respectively. This is YiPhase’s stated two-number convention; no hour number is silently added.
Mei Hua from a moment: the selected time zone is used to derive the lunar date and traditional two-hour period. The year-branch number, lunar month and lunar day select the upper trigram; adding the hour-branch number selects the lower trigram and changing line. A leap month uses its numbered month. The result shows the actual arithmetic so it can be checked.
Body and use: the trigram containing the changing line is use; the other is body. Their Five Phase relationship gives the opening judgment. The same original cast continues into the free I Ching Deep Reading preview; continuing does not cast again. Lines are counted from the bottom.
Three coins: the separate coin path builds six lines from six casts. Heads count three and tails two. Totals six and nine change; seven and eight remain. It follows the hexagram and its actual changing lines, without imposing the Mei Hua body/use method.

Who is speaking, and what is illustrated?
Jackie shares his interest in the I Ching and its use in everyday observation. YiPhase’s editorial explanations, contemporary examples and teaching illustrations help readers enter the subject; they are not additional ancient texts or claims of a professional qualification.
AI tools assist with parts of the site’s writing, artwork and lesson production. Some earlier lessons use Jackie’s approved digital presenter and synthetic narration; newer illustrated lessons use pictures, diagrams and narration. A digital presentation is not a live conversation or a personal reply from Jackie.
Collection pages distinguish the three actual, one-of-one stones and bracelets from styling possibilities. An agate shown as a pendant illustrates an optional use: the offered piece is an unmounted stone. Enquiries do not create an order or reservation; checkout is not open.
Your question and the limits of a reading
YiPhase forms the cast in your browser using the stated rules. When you select Start My Free Reading on the free reading page, your question and cast are sent over HTTPS to YiPhase and its AI provider to generate the interpretation. The legacy coin and moment pages send the question and cast when you choose an AI explanation. Sending data for interpretation is different from saving it: your current question, cast, answer and notes you choose to save are retained in this tab’s session storage, not as reading records in YiPhase’s server database. They can survive refresh and same-site navigation; download a copy for longer retention. Clearing the current reading removes this flow’s tab data and notes, not downloaded files, older studio records, Learning Circle drafts, server connection logs or data held by the AI provider. See the privacy notice for the exact clearing controls and retention details.
Start with the interpretation of your question, then open the classical text and learning material if you want to understand its basis. A reading cannot establish another person’s thoughts or replace real-world evidence. This is cultural education and personal reflection, not medical, legal or financial advice.
