[299] Bhikkhus, there is a further case. Just as if a bhikkhu were to see a corpse discarded in a charnel ground (sīvathikā)—one day dead, or two days dead, or three days dead—bloated, livid, and festering, he compares this very body with it: 'This body too is of such a nature, it will come to be thus, it has not gone beyond this.' As he dwells thus, diligent, ardent, and resolute, whatever memories and thoughts (sarasaṅkappā) connected with the household life there are, they are abandoned. With the abandoning of these, his mind (citta) becomes steadied internally, settles down, becomes unified, and becomes concentrated. Thus too, bhikkhus, does a bhikkhu develop mindfulness directed to the body (kāyagatā sati).
