And again, a bhikkhu examines and reflects closely upon this very body, from the soles of the feet up and from the tips of the head hair down, enclosed by the skin and full of various kinds of impurities,

“There exists in this body: hair of the head, hair of the body, nails, teeth, skin, flesh, sinews, bones, marrow, kidneys, heart, liver, membranes,spleen, lungs, intestines, mysentery, gorge, faces, brain, bile, phlegm, pus, blood, sweat, solid fat, tears, liquid fat, saliva, mucus, synovic fluid and urine.”

Just as if there were a double-mouthed provision bag filled with various kinds of grain such as: hill-paddy, paddy, green-gram, cow pea, sesamum, and husked rice; and a man with sound eyes, having opened it, should examine it thus:

“This is hill-paddy, this is paddy, this is green-gram, this is cow pea, this is sesamum, and this is husked rice.”

Just so, a bhikkhu examines and reflects closely upon this very body, from the soles of the feet up and from the tips of the head hair down, enclosed by the skin and full of various kinds of impurities,

“There exists in this body: hair of the head, hair of the body, nails, teeth, skin, flesh, sinews, bones, marrow, kidneys, heart, liver, membranes, spleen, lungs, intestines, mysentery, gorge, faces, brain, bile, phlegm, pus, blood, sweat, solid fat, tears, liquid fat, saliva, mucus, synovic fluid and urine.”

Thus he dwells perceiving again and again the body as just the body, not mine, not I, not self, but just a phenomenon, in himself; or he dwells perceiving again and again the body as just the body in others ; or he dwells perceiving again and again the body as just the body in both himself and in others. He dwells perceiving again and again the cause and the actual appearing of the body; or he dwells perceiving gain and again the cause and the actual dissolution of the body; or he dwells perceiving again and again both the actual appearing and dissolution of the body with their causes.

To summarize, he is firmly mindful of the fact that only the body exists, not a soul, a self or I. That mindfulness is just for gaining insight and mindfulness progressively. Being detached from craving and wrong views he dwells without clinging to anything in the world.

Thus, this is a way in which a bhikkhu dwells perceiving again and again the body as just the body.
