Being.
I learned that I can not just observe myself breathing, but be the breather, the nose, the throat and lungs. I can be aware of some of the air filling the space around me, filling my lungs and then being expelled back into the air around me.
Such a miraculous process of drawing matter from outside my body, into my lungs to absorb oxygen to nourish this amazing living being that is me, and then using the muscles of my respiratory system to push that matter back out of my lungs and into the air/matter around me.
Amazing! 😊
