復次，諸比丘！比丘思惟此身，自足底而上、由頭髮而下，皮所覆包，遍滿不淨，思惟：於此身有髮、毛、爪、齒、皮、肉、筋、骨、髓、腎、心、肝、肋膜、脾、肺、腸、腸間膜、胃中物、糞、膽汁、痰、膿、血、汗、脂肪、淚、皮脂、唾、涕、關節液、尿。
諸比丘！猶如兩端開口之糧袋，裝入種種穀物，諸如：稻、米、綠豆、豌豆、芝麻、精米。視力佳者， 解開糧袋，觀察分辨：此是稻、此是米、此是綠豆、此是豌豆、此是芝麻、此是精米。
如此，諸比丘！比丘思惟此身，自足底而上、由頭髮而下，皮所覆包，遍滿不淨，思惟：於此身有髮、毛、爪、齒、皮、肉、筋、骨、髓、腎、心、肝、肋膜、脾、肺、腸、腸間膜、胃中物、糞、膽汁、痰、 膿、血、汗、脂肪、淚、皮脂、唾、涕、關節液、尿。
10. “Again, bhikkhus, a bhikkhu reviews this same body up from the soles of the feet and down from the top of the hair, bounded by skin, as full of many kinds of impurity thus: ‘In this body there are head-hairs, body-hairs, nails, teeth, skin, flesh, sinews, bones, bone-marrow, kidneys, heart, liver, diaphragm, spleen, lungs, large intestines, small intestines, contents of the stomach, feces, bile, phlegm, pus, blood, sweat, fat, tears, grease, spittle, snot, oil of the joints, and urine.’
Just as though there were a bag with an opening at both ends full of many sorts of grain, such as hill rice, red rice, beans, peas, millet, and white rice, and a man with good eyes were to open it and review it thus:
‘This is hill rice, this is red rice, these are beans, these are peas, this is millet, this is white rice’; so too, a bhikkhu reviews this same body … as full of many kinds of impurity thus: ‘In this body there are head-hairs … and urine.’
如是，比丘安住於身，觀照內身；安住於身，觀照外身；安住於身，觀照內外身。安住於身，隨觀生法；安住於身，隨觀滅法；安住於身，隨觀生滅法。
於是「有身」之念現起，唯有正念與覺照，無所依而住，不再貪著世間之任何事物。
諸比丘！此即比丘安住於身，循身觀察。
11. “In this way he abides contemplating the body as a body internally, externally, and both internally and externally … And he abides independent, not clinging to anything in the world. That too is how a bhikkhu abides contemplating the body as a body.
