BaZi, also known as Four Pillars of Destiny, is a Chinese astrological system that uses the five elements of Earth, Metal, Water, Wood, and Fire to understand a person’s personality and life events. These elements are present in two forms – yin and yang – and make up the 10 heavenly stem elements. Your self-element, which is determined by the element in the day pillar of your birth chart, is a crucial aspect of your BaZi analysis. In addition to your self-element, the other three pillars – the month, year, and hour pillars – also play a role in shaping your personality and life events. Therefore, while your self-element is important, it is only one part of the bigger picture in your BaZi analysis.
