Firstly, some ascetic or brahmin—by dint of keen, resolute, committed, and diligent effort, and right application of mind—experiences an immersion of the heart of such a kind that they examine their own body up from the soles of the feet and down from the tips of the hairs, wrapped in skin and full of many kinds of filth. ‘In this body there is head hair, body hair, nails, teeth, skin, flesh, sinews, bones, bone marrow, kidneys, heart, liver, diaphragm, spleen, lungs, intestines, mesentery, undigested food, feces, bile, phlegm, pus, blood, sweat, fat, tears, grease, saliva, snot, synovial fluid, urine.’ This is the first attainment of vision. Furthermore, some ascetic or brahmin experiences that immersion and examines their own body. ‘In this body there is head hair … urine.’ Going further, they examine a person’s bones with skin, flesh, and blood. This is the second attainment of vision. Furthermore, some ascetic or brahmin experiences that immersion and examines their own body. ‘In this body there is head hair … urine.’ Going further, they examine a person’s bones with skin, flesh, and blood. And they understand of a person that their stream of consciousness is consistent on both sides: established in both this world and the next. This is the third attainment of vision.
