Body Buddhist Scripture

 46. Realizing that this body is like froth, penetrating its mirage-like nature, and plucking out Mara's flower-tipped arrows of sensuality, go beyond sight of the King of Death!

"Furthermore, the monk reflects on this very body from the soles of the feet on up, from the crown of the head on down, surrounded by skin and full of various kinds of unclean things: 'In this body there are head hairs, body hairs, nails, teeth, skin, flesh, tendons, bones, bone marrow, kidneys, heart, liver, pleura, spleen, lungs, large intestines, small intestines, gorge, feces, bile, phlegm, pus, blood, sweat, fat, tears, skin-oil, saliva, mucus, fluid in the joints, urine.' Just as if a sack with openings at both ends were full of various kinds of grain — wheat, rice, mung beans, kidney beans, sesame seeds, husked rice — and a man with good eyesight, pouring it out, were to reflect, 'This is wheat. This is rice. These are mung beans. These are kidney beans. These are sesame seeds. This is husked rice'; in the same way, the monk reflects on this very body from the soles of the feet on up, from the crown of the head on down, surrounded by skin and full of various kinds of unclean things: 'In this body there are head hairs, body hairs, nails, teeth, skin, flesh, tendons, bones, bone marrow, kidneys, heart, liver, pleura, spleen, lungs, large intestines, small intestines, gorge, feces, bile, phlegm, pus, blood, sweat, fat, tears, skin-oil, saliva, mucus, fluid in the joints, urine.' And as he remains thus heedful, ardent, & resolute, any memories & resolves related to the household life are abandoned, and with their abandoning his mind gathers & settles inwardly, grows unified & centered. This is how a monk develops mindfulness immersed in the body.

With mindfulness immersed in the body well established, restrained with regard to the six media of contact — always centered, the monk can know Unbinding[1] for himself.

41. Ere long, alas! this body will lie upon the earth, unheeded and lifeless, like a useless log.
