A slow exhale activates the parasympathetic nervous system
The "physics" of the Kingdom often begins with the breath—the Ruach (Hebrew for breath, wind, or spirit). In Genesis, life begins when the Ruach is breathed into the form. By slowing the exhale, you are moving from the "striving" of the flesh into a state of Sabbath rest (Shabbat) at a cellular level. It is the physical manifestation of "Be still, and know" (Psalm 46:10), allowing the internal noise to settle so the "Still Small Voice" of the Kingdom OS can be heard over the Empire’s roar.
