"Rahula, whatever internally, belonging to oneself, is solid, solidified, and clung-to, that is, 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, or whatever else internally, belonging to oneself, is solid, solidified, and clung-to: this is called the internal earth element. Now both the internal earth element and the external earth element are simply earth element. And that should be seen as it actually is with proper wisdom thus: “This is not mine, this I am not, this is not my self.” When one sees it thus as it actually is with proper wisdom, one becomes disenchanted with the earth element and makes the mind dispassionate towards the earth element."
