[298] Bhikkhus, again, further, a bhikkhu reviews this very body—however it is placed, however it is disposed—in terms of elements (dhātu): 'There are in this body the earth element, the water element, the fire element, the air element.' Bhikkhus, just as a skilled butcher of cattle or a butcher's apprentice, having slaughtered a cow, might sit at the crossroads of four great highways, having divided it up into portions; even so, bhikkhus, a bhikkhu reviews this very body—however it is placed, however it is disposed—in terms of elements: 'There are in this body the earth element, the water element, the fire element, the air element.'
As he dwells thus, diligent, ardent, and resolute, those memories and thoughts connected with the household life are abandoned. With their abandoning, his mind (citta) becomes steady internally, settles down, becomes unified, and is concentrated. Thus too, bhikkhus, a bhikkhu develops mindfulness directed to the body (kāyagatā sati).
