7.27

Below, where it clarifies 'when mindful of a short in-breath, one takes this intermediate in-breath as cognitive object, and the out-breath is likewise', etc.: initially emerging from the navel up to the mouth and nose, or exiting outside the nose, this is a long out-breath; when the out-breath has ceased and the in-breath has not yet arisen, in the interim from the navel to the nose there is momentarily a wind resembling the out-breath.
