Useful God — the key balancing element in Bazi

Meaning and Context

The Useful God is the element most beneficial for a particular chart. Its selection depends on the Day Master's strength, the season of birth, and overall elemental distribution.

  • For weak Day Master: Often the element that supports it (same element or Resource)
  • For strong Day Master: Often the element that drains or controls it (Output, Wealth, or Power)
  • Must consider chart structure holistically, not just Day Master strength

Classical Roots

From Yuanhai Ziping
「用神者,命之枢纽也。」
Plain translation
"The Useful God is the pivot of destiny." This emphasizes its central importance in chart analysis and life guidance.

Selection Framework

Selecting the Useful God involves:

  • Assess Day Master strength in seasonal context
