I have been practicing Embryonic Breathing according to the instructions given in "Qigong Meditation: Embryonic Breathing".
I am confused about the movement of the diaphragm in reverse breathing/embryonic breathing.
When breathing in, as the lower belly and lower back move towards each other and the the perineum goes up, should the diaphragm go up (relsease/dome), down (contract/flatten), or not move at all ?
When breathing out, as the lower belly and lower back release (move away from each other) and the perineum releases down, should the diaphragm go (relsease/dome), down (contract/flatten), or not move at all ?
I searched the book and online but could not find a definitive answer.
It makes sense to me for the diaphragm to move in embryonic breathing in the same way it moves in normal breathing, that is contract/flatten on the inhale. In this way the inhale will create compression on the lower dan tien from all directions. I have been practicing like that for a while.
However I want to get confirmation to this from Dr Yang or a senior teacher, or is there a written resource which describe this clearly ?
Thank you !
