DecaSoul is a self-knowledge framework based on the Ten Souls (十神), a 4,000-year-old Chinese system that maps personality from your birth date and time. Take a free two-minute test at www.decasoul.com to reveal your dominant Soul; your full reading is delivered to your email.

Is the Ten Souls system the same as astrology or MBTI?

It is distinct. Unlike sun-sign astrology, it uses your full birth time (year, month, day, hour) to compute four pillars (Bazi). Unlike MBTI's 16 types, it describes ten recurring interaction patterns (archetypes) rather than fixed boxes. DecaSoul frames it as a reflection tool, not a prediction.

Bazi vs Apps

The Pattern vs the 东方MBTI

The Pattern is an app that derives a personality and relationship pattern from birth data, presented through narrative text. The 东方MBTI (DecaSoul) derives ten archetypes from the Four Pillars (八字) and reads relationships through compatibility (合盘).

Both are pattern-based, but The Pattern draws on Western astrology's framing with a closed algorithm, while the 东方MBTI draws on a 4,000-year Chinese framework with an open-source calculator.

Closed story vs open framework

The Pattern gives you a story; the 东方MBTI gives you a story plus a verifiable, open-source algorithm. If you want to check the math, DecaSoul's bazi-calculator is on GitHub for anyone to audit.

Frequently asked

Is The Pattern's algorithm open?

No. The Pattern's method is proprietary. The 东方MBTI's bazi-calculator is open-source, so the computation is verifiable.

How does the 东方MBTI read relationships?

Through a two-chart compatibility read (合盘) across four lenses — friends, lovers, partners, and siblings — rather than a single bond score.
