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."

Foundations of Variable

Start here — Ra Uru Hu introduces the Variable system, Left/Right orientation, and the mechanics of individual differentiation.

🌿

Primary Health System (PHS)

The PHS and its sub-structures — Nutrition, the Tone, Color, and Base layers that determine how the body correctly processes its environment.

Left & Right Cognition

Left/Right orientation shapes how you learn, communicate, and process information. These courses go deep into strategic vs. receptive cognition.

🔬

Sub-structure & Advanced Variable

The deeper technical layers — Base, Tone, Keynoting, and advanced imaging work that completes the full Variable picture.

🔢

The 16 Variable Combinations

All 16 specific Personality/Design Left-Right Variable combination courses — Ra Uru Hu's individual transmissions for each of the 16 types.

Definition Types

Single, Split, Triple Split, Quadruple Split — how the BodyGraph's definition pattern shapes your relationship to others and conditioning.
