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 Systems

Human Design vs Bazi

Human Design is a system synthesizing astrology, the I Ching, Kabbalah, and the chakras into a bodygraph, created in 1987. Bazi (八字) is a Chinese system computing the Four Pillars from birth time — the engine of the 东方MBTI.

Human Design mixes multiple Western and esoteric traditions. Bazi is a single, coherent 4,000-year Chinese tradition rooted in the I Ching's yin-yang and the Five Elements.

Syncretism vs lineage

Human Design borrows from the I Ching; Bazi is the I Ching's own descendant. That difference matters if you want a framework with a single coherent root rather than a modern synthesis.

Dimension	Human Design	Bazi (东方MBTI)
Origin	1987, syncretic	~4,000 years, Chinese
Core input	Birth time + place	Birth year / month / day / hour
Output	Bodygraph (5 types)	Four Pillars → Ten Souls
Cultural root	Mixed (astrology + I Ching + chakras)	Pure Chinese (I Ching + Five Elements)

Frequently asked

Is Human Design related to Bazi?

Only indirectly. Human Design borrows the I Ching's hexagrams, but Bazi is the I Ching's direct descendant through the Five Elements.

Which is older?

Bazi, by far. Human Design was created in 1987; Bazi's lineage runs roughly 4,000 years.
