Heart–brain coherence

Scientific evidence of spiritual alignment.

Why it matters

When heart rhythm, breath and emotion synchronise, the whole system transmits one stable signal — measurable as HRV coherence.

Measured in the Medicine 3.0 baseline and re-tested once the protocol has run.

The body it belongs to

Purpose, spirit and inner energy — and the metabolic fire that powers them.
