Last night I was starting out on my side and was getting a delicious sensation about midway of the north south excursion.
As I inhaled it would pass over and then stop, causing abdominal shuddering while I held my breath. Then as I exhaled, I could feel it ride over the same spot.
So I tried holding my ‘push’ and ‘pull’ at the magic point.
I got it locked on for a bit and experienced a rapidly expanding sort of numbing buzzing sensation throughout my torso.
Unfortunately, it was over in about 8 or 10 seconds.
Never could get back to it.

Alas, new thing = progress!

Press on.
