Take a deep breath. Some thoughts following not yet fully formed...
Looking into the concept of breathing, I found a link to meanings of the word psyche.
psyche
1. Breath, to breathe, to blow, (later) to cool; hence, life (identified with or indicated by the breath); the animating principle in man and other living beings, the source of all vital activities, rational or irrational, the soul or spirit, in distinction from its material vehicle, the body; sometimes considered as capable of persisting in a disembodied state after separation from the body at death.
2. In Mythology, personified by Plato and other philosophers, it was extended to the anima mundi, conceived to animate the general system of the universe, as the soul animates the individual organism.
3. The soul, or spirit, as distinguished from the body; the mind.
4. The conscious and unconscious mind and emotions; especially, as influencing and affecting the whole person.
5. All that constitutes the mind and what it processes.
6. Term for the subjective aspects of the mind, self, soul; the psychological or spiritual as distinct from the bodily nature of humans.
This takes my thoughts to where they still too-often go these days, even after almost four months of not smoking. Apart from the occasional lava-lamp bubbling beneath my brain, without thought or warning will come a sudden in and out of a sharp breath from my mouth. Someone else noticed this, thinking I was practicing some kind of meditative zen technique. What actually went on: my body tries to smoke, even without a cigarette in hand. Breathe in and puff out. Therefore, by the definitions above, the mere act of breathing constitutes expelling our life force, our animating spirit.
When I get the chance, I put these exhalations to work as I finally found something, like smoking, involving breathing in and out and annoying people at the same time: playing the harmonica.
To play all the notes in the scale you alternate breathing in and out like in the image below.
And once again mixing some of the definitions above together the spirit, the unconscious mind get translated into the vibrations created by the ‘blows’ and ‘draws’ – in this act they become something else.
