Nayin and the Three Yuan: Two Historical Models That Should Not Be Blended
Three yuan does not always denote one timeless diagram. Relevant Wuxing Jingji passages connect upper, middle and lower origins with stem, branch and Nayin (a separate named element classification for a complete pair of chart symbols). Sanming Tonghui volume 2, in its Human-Origin discussion, describes Heaven as stems, Earth as branches and Human as the seasonally active stems hidden in the Month Branch (the lower symbol in the birth-month column). The source must be identified first.
What occupies the three levels in each source?
Wuxing Jingji’s three-yuan discussion and nearby passages use older Lu Ming language in which stems, branches and Nayin occupy the three levels, including upper stem, middle branch and lower Nayin. Sanming Tonghui volume 2 explains Heaven, Earth and Human through stems, branches and seasonally active hidden stems (the additional element symbols traditionally assigned inside each lower chart symbol) in the Month Branch.
Both document historical vocabulary. They do not justify placing lower-origin Nayin and hidden-stem Human Origin into one supposedly universal three-level chart.
| Source | First level | Second level | Third level | Context |
|---|---|---|---|---|
| Wuxing Jingji passages | Upper: stem | Middle: branch | Lower: Nayin | Lu Ming stem, branch and body classification |
| Sanming Tonghui vol. 2 | Heaven: stems | Earth: branches | Human: Month-Branch hidden stems | Seasonal command and hidden participation |
How do 甲子 and a Yin month return to their sources?
In the Wuxing Jingji context, 甲子 can be recorded as Jia stem, Zi branch and Gold-in-the-Sea Nayin within an older stem–branch–Nayin model. In Sanming Tonghui’s Human-Origin context, a Yin month calls for its hidden stems and seasonal sequence inside the Month Branch.
These are two examples, not one merged chart. The word Human Origin does not give every 甲子 one universal hidden-stem verdict, and Year Gold in the Sea does not thereby govern all Four Pillars (the chart’s four birth-time columns: year, month, day and hour).
Can historically important Year Nayin become a life keynote?
Lu Ming texts can give year-life, Nayin and host–self relations substantial weight, but every text still has its terms, participants and conditions. A modern page can say that a source prioritizes year-life without upgrading an image into a verified life temperament, rise-and-fall pattern or fate guarantee.
How does this differ from Day-Master and Month-Command Zi Ping?
Yuanhai Ziping explicitly centers the Day and treats the Month as the governing outline before examining strength, phases and structure. Learners can compare the source models, but each should be completed independently. Human-Origin seasonal duty and modern fixed hidden-stem tables also need declared conventions.
Ask what three yuan means in the cited passage, record its units and evidence order, and only then compare another system. This preserves history without inventing one blended algorithm that the sources did not jointly define.
