What is a day master?

In the Chinese Four Pillars (BaZi), your birth is written as four pairs of characters for the year, month, day and hour. The heavenly stem of the day pillar is the day master: the character that stands for you. There are ten, one for each element in a yin and a yang form.

How the other elements treat Water

In the Four Pillars every other character in your chart is read by its relationship to the day master. The five relationships are the grammar of the whole system.

Companion. The same element as you: peers, siblings, competition and self-reliance; more of you, for better and worse.
Resource. The element that feeds you: learning, support, mothers and mentors, rest; nourishing, and in excess it makes you passive.
Output. What you produce: expression, creativity, children, talent and performance; what you put into the world.
Wealth. What you control: money, assets, results, and for men the partner; ambition and the effort it takes.
Power. What controls you: authority, career, discipline, pressure, and for women the partner; status earned under constraint.
