This is the master directory for the BaZi Day Master × Auxiliary Star (神煞) matrix. Shen sha are classical BaZi auxiliary stars derived from the chart’s pillars; their presence in a specific chart modulates the Day Master’s register, the Ten God configurations, and the chart’s overall reading. The 100 configurations in this matrix describe how each of the 10 commonly-watched shen sha reads when present in the chart of each of the 10 Day Masters.
Voice constraint: these pages name each configuration (e.g., 甲日主見天乙貴人) and describe its register; they do not teach the procedure for identifying which shen sha land in a specific chart (the derivation rules), or how to read shen sha against pillar placement and luck pillars. For chart-aware reading, book a BaZi consultation; for self-study, use the free BaZi Calculator; for learning the shen sha doctrine in depth, the BaZi Bootcamp covers it from beginner through intermediate.
⚠️ Why a generic shen sha guide is not enough
A complete shen sha reading layers four inputs:
- Whether the shen sha lands in the chart at all (derivation gating).
- Which pillar it lands on (year / month / day / hour) — determines life-domain.
- Modulation by the Ten Gods active on that pillar.
- The chart’s overall strength + Useful God + active luck pillar.
This matrix describes the first input. Use it as a classical starting reference, not a final reading.
The 10 commonly-watched shen sha

How to read this matrix against your own chart
- Plot the four pillars via the BaZi Calculator. The day pillar's heavenly stem is the Day Master.
- Note which shen sha actually derive from your chart. The calculator highlights the auxiliary stars present in your specific chart.
- Look up each present shen sha in the matrix above (under your Day Master). The cell describes its classical baseline register.
- Apply the four-input framework. Pillar placement + Ten God modulation + chart strength + luck pillar all modulate the baseline register.
- Book a chart-aware consultation via BaZi consultation to integrate the four inputs for a full reading.
