- Survival, instincts, and fears
energetics of the spleen energy center
- The Spleen Energy center is all about survival and helping us stay alive.
- In Human Design, our instincts live in the spleen and not the gut, which is excited by and associated with desire/creativity.
- Fears that live inside the spleen are basic for survival.
- Fear is the lowest expression of any line at the bottom. Every gate, if used the wrong way, turns into a fear. If you have fear, you haven’t developed your intuition enough.
biological association
- Immunity and the lymphatic system
defined spleen energy center

undefined (open) spleen energy center
- Anxiety is not a helpful driver for this individual.
