How BaZi Works · 101

Stems = Actors
Pure elements; Day Stem = self.
Branches = Containers
Environment, hidden stems, season.
Ten Gods = Relationships
Names of interactions relative to Day Stem.
Interactions = Story
Clashes, combinations, Luck Pillars, annual pillars.
SummaryStems = who acts. Branches = where and why. Ten Gods = what it means to you. Clashes/combinations = how energy moves. Luck Pillars = when things activate.
命由天定,运由己生
