In meditation I am experimenting with the two phrases “Breath of the Body” and “Body of the Breath”

I find that it is quite enough to absorb myself in the breath if when I inhale and say “body of the breath” I am feeling the touch of air as it fills my body, and then say “body of the breath” as I exhale and feel touch of air leave my body. Then, say “breath of the body” as I inhale and feel all the muscle tension and expansion and movement of the body that is involved opening the body for the in-breath. Finally, say “breath of the body” as I exhale and feel my lungs and chest fall to a resting, closed place. I have had some interesting experiences as I practice this meditation technique, but will post more if there is anything more I can share.
