Regarding 'wherever it operates': this recapitulates and concludes the meaning of the four kinds of counting above, such as counting one as one; 'up to however it operates' concludes the progressive counting above; 'as it operates' concludes that upon confusion one should regress and start from one again; 'at whatever time it operates' concludes that when counting is extremely well practiced, one knows presence and knows absence, etc.; regarding 'in all these, due to mindfulness being stably positioned', etc., it concludes the statement 'thus sequentially and continuously flowing up to causing the mind to abide stably', etc. Tai says: 'The various apertures are called "wherever it operates"; entering the body down to the navel-wheel is called "up to however it operates"; conforming to the in-and-out breaths is called "as it operates"; the successive long or short durations of the in-and-out breaths are called "at whatever time it operates".'
