LUNG 6: How penetrable are you? How easily do things permeate you from the outside? How shielded or protected from the storms that rage around you do you feel on the inside? Lung 6 is a strong regulator of our personal permeability in life. Whenever anything changes in the interior or the exterior, our whole pattern of the relationship between interior and exterior needs to be able to change fluidly, intelligently, freely. Lung 6 is the highly sensitive, very quick emergency regulatory function of how open or how closed we are to the world around us.
