Let the body breathe on its own!
Let the body breathe on its own. Have you realized how tense the stomach is/can be and how we try to regulate/control the breath? This can be best noticed when doing the awareness of breath (ana-pana-sati) meditation. So rather than trying to breathe, relax the body and especially the stomach and let the body breathe on its own, in its own time, in its own way.
It will be less painful and more pleasant this way.
