How Human Design differs from astrology and why they complement each other.
Common Roots, Different Fruits
HD uses planet positions — just like astrology. But Ra Uru Hu integrated I Ching, Kabbalah, chakras, and quantum physics.
7 Differences
1. Two Calculations vs One
Astrology: one moment (birth). HD: two — Personality + Design (~88 days before), revealing the unconscious.
2. I Ching Instead of Zodiac
12 signs × 30° = 360° vs 64 hexagrams × 6 lines = 384 positions — far more precise.
3. Body as Priority
Astrology — psychological focus. HD — body is authority: sacral response, intuition, emotional wave.
4. Strategy and Authority
Astrology describes tendencies. HD gives a specific decision-making mechanism.
5. Not-Self as Diagnostics
Open centers create specific Not-Self themes — frustration, anger, bitterness — as indicators.
