What Are Luck Pillars in BaZi? (10-Year Cycles Explained)

Luck Pillars in BaZi are 10-year cycles that show how your life conditions change over time. While your birth chart (Four Pillars) is fixed, Luck Pillars explain when opportunities, challenges, and major life shifts occur.
This matters because BaZi is not only about structure it is about timing. Understanding Luck Pillars allows you to align decisions with favorable periods and avoid acting against unfavorable cycles.
