"Tell me, if you don't mind, what happens..."
No, I don't mind! However, I'm not sure if I understand the question correctly, but rather than asking you to elaborate I gave it a go (two really) first, so then you can get a good laugh and/or give any necessary further explanation.
On my first try nothing really happened, exept I had my hands (and mind) full with getting my body to comply with your instructions
I felt warmth though.
You said nothing about posture or position of hands etc. so I figured it didn't matter that much.
Second time I tried I basically felt up- and downward expansion/extension while inhaling and ditto sideways while exhaling.
Tell me, if you don't mind, why would you ask a (seemingly?) strange question like that?
