BaZi 八字

八字 ba zi: the eight characters, four pillars of two characters each.

Eight characters, four pillars, one per unit of time you were born into. BaZi reads a life through the five elements in relation to one another.

What it is

BaZi takes the year, month, day and hour of a birth and writes each as two characters, a heavenly stem above an earthly branch. The stem of the day pillar is the day master, and it is the reference point everything else is measured against.

What the system is good at is balance and timing. What do you have too much of, what are you short of, and which stretches of time support you. That focus is why a BaZi reading tends to arrive at a decision rather than a description.

The ten day masters and the ten gods

Two reference sets carry most of the weight. The ten heavenly stems, one of which is your day master, and the ten gods, which name what each other character is to you: support, rivalry, output, pressure, opportunity.
