Variable, PHS & Definition Types

The most advanced layer of differentiation in Human Design — Ra Uru Hu's original transmissions on the 16 Variable combinations, Primary Health System (PHS), Left/Right orientation, Color, Tone, Base sub-structure mechanics, and the four Definition types. Curated by Dr. LaVeena B. Archers, Official Affiliate with 14+ years of study.

16 Variable Combinations

6 Topic Groups

Prerequisite notice: Variable and PHS are advanced topics. Dr. LaVeena recommends completing Advanced 1: Left, Right & the 16 Variables and Advanced 2: The Four Transformations before diving into the individual Variable combination courses. See the full library for the complete recommended study path.

Dr. LaVeena's Note

"Variable is the most under-studied and misunderstood area of Human Design. Most people who 'know their type' have never engaged with their Variable — and yet this is where the real differentiation lives. The 16 Variable combinations, the PHS, and the sub-structure mechanics determine how your body correctly interfaces with the world. Ra Uru Hu's transmissions here are irreplaceable. There is no adequate secondary source."
