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.

Sub-structure & Advanced Variable

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

🔢
