The Life Palace is an auxiliary concept in BaZi astrology, calculated through a specific method as a virtual palace representing the native's mental world and inner characteristics. Analyzing the Life Palace in conjunction with the Four Pillars provides a more comprehensive understanding of the native's personality and life trajectory.
Method to determine the Life Palace: Subtract the sum of the Earthly Branch of the Year Pillar and that of the Month Pillar from the sum of the Earthly Branch of the Day Pillar and that of the Hour Pillar; the remainder corresponds to the Earthly Branch of the Life Palace. Alternatively, one may count forward from the Zi (Rat) hour of the birth month to the birth hour. Calculation methods vary slightly among different schools.
For a person whose Life Palace is Yin (Tiger), and whose Day Master is Jia Wood, Yin Wood represents the Day Master’s Prosperity Position, indicating a rich mental world and strong inner vitality.
