Compare mantic systems
Read systems against shared questions to identify common language, procedural differences and distinct limits.
| Dimension | 奇门遁甲 ↗ | 大六壬 ↗ |
|---|---|---|
| Family | The Three Cosmic Boards and spatiotemporal methods | The Three Cosmic Boards and spatiotemporal methods |
| Inputs | Time, solar term, dun mode, board convention and arrangement method | Day stems-branches, monthly general, hour and transmission rules |
| Procedural structure | Season and date determine yin or yang rotation and configuration number, after which earth, heaven, human and spirit layers are arranged. Interpretation centers on day, hour or topic signs and compares palace, gates, stars, spirits, seasonal strength and pattern. | After the monthly general is placed over the hour, four relations are derived from the day stem and branch. Rule families such as overcoming, matching, depth and remote control select three transmissions, which are read with twelve generals, natal signs and pattern classes. |
| Formation | The name Dunjia is Han-attested; received systems formed from Tang-Song through Ming-Qing | Han cosmic boards form an early background; mature textual systems are confirmed by Tang-Song |
| Evidence labels | Textually documented · Traditional attribution · Contested lineage or date | Excavated evidence · Textually documented · Contested lineage or date |
| Texts | Dunjia Fuying Jing / Dunjia Yanyi / Imperially Commissioned Qimen Baojian / Dunhuang Dunjia materials | Jingyou Liuren Shending Jing / Liuren Daquan / Liuren Zhinan / Liuren Case Judgments |
| Limits | Lineages involving Feng Hou, 1,080 original configurations, Zhuge Liang or Liu Bowen are later narratives. Competing calendrical rules produce different charts; no universally accepted single algorithm exists. | A Han board does not prove that the entire received system already existed. Transmission-selection rules are complex and vary in details by school. |
| Research question | Where do board selection and interpretation diverge? | Can the selection from lessons to transmissions be reproduced? |
