What is Ba Zi?
Ba Zi — literally "eight characters" — is a Chinese system for reading personality, timing, and circumstance from your birth date and time. Where Western astrology uses planetary positions, Ba Zi uses the ancient cycle of the five elements as they appear across four distinct pillars.
Your Day Pillar's Heavenly Stem is your elemental archetype — one of ten. It shapes how you think, what you want, and what tends to trip you up. Arka identifies yours and builds everything around it.
