Si Ling, Si Quan, and Si Ming in Bazi (司令、司權與司命)
Compare 司令, 司權, and 司命 in Bazi, see how schools use these Month Command terms, and learn how to disclose the adopted meanings without mixing frameworks.
Overview
Si Ling, Si Quan, and Si Ming (司令、司權、司命) are related but not universally standardized terms used to discuss monthly qi. A practical distinction is: 司令 identifies the qi governing a segment, 司權 describes seasonal authority, and 司命 emphasizes the Month Command’s organizing role. Classical lineages and modern schools sometimes assign them differently, so a reliable page defines its vocabulary before applying it.
At a glance
- 司令
- Often the qi governing a specific seasonal segment
- 司權
- Often the authority held by seasonal qi
- 司命
- Often the command’s organizing role in analysis
- Variation
- Definitions differ across texts and schools
- Best practice
- Define the adopted usage before calculation
- Limit
- Not three universally fixed numerical variables
Treat the three labels as declared vocabulary
These expressions share the language of governing or administering qi, but historical and modern authors do not always draw the same boundaries between them.
Quote or name the adopted source tradition where precision matters. An unexplained label cannot carry a reproducible calculation.
- Define each term locally.
- Do not imply universal consensus.
Use a practical distinction without erasing variants
司令 can identify which hidden qi governs the current subperiod; 司權 can describe the seasonal leverage it receives; 司命 can describe the Month Command’s organizing priority.
This working distinction helps separate identity, force, and analytical role. It remains a methodology choice rather than a recovered physical law.
- Separate governing qi, authority, and role.
- Label the distinction as methodological.
Connect every term to observable chart data
Link 司令 to the exact term segment and hidden-stem table, 司權 to seasonal relations, and 司命 to the order in which strength or structure is assessed.
If a school uses a different mapping, preserve its own definitions consistently across examples and tools.
- Attach labels to explicit inputs.
- Keep one vocabulary per calculation path.
Do not multiply certainty through terminology
Using three technical names does not make an interpretation three times more certain. Their value is organizational and comparative.
Do not turn these labels into claims about command, fate, social power, or divine mandate in a person’s life.
- Technical density is not evidence.
- No literal authority claim.
