The Middle Length Discourses of the Buddha - Bhikkhu Nanamoli [521]
11. “‘Bhikkhu, this person has four foundations.’ So it was said. And with reference to what was this said? There are the foundation of wisdom, the foundation of truth, the foundation of relinquishment, and the foundation of peace.1270 So it was with reference to this that it was said: ‘Bhikkhu, this person has four foundations.’
12. “‘One should not neglect wisdom, should preserve truth, should cultivate relinquishment, and should train for peace.’1271 So it was said. And with reference to what was this said?
13. “How, bhikkhu, does one not neglect wisdom?1272 There are these six elements: the earth element, the water element, the fire element, the air element, the space element, and the consciousness element.
14. “What, bhikkhu, is the earth element? The earth element may be either internal or external. What is the internal earth element? 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, intestines, mesentery, 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.
15. “What, bhikkhu, is the water element? The water element may be either [241] internal or external. What is the internal water element? Whatever internally, belonging to oneself, is water, watery, and clung-to, that is, bile, phlegm, pus, blood, sweat, fat, tears, grease, spittle, snot, oil-of-the-joints, urine, or whatever else internally, belonging to oneself, is water, watery, and clung-to: this is called the internal water element. Now both the internal water element and the external water element are simply water 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 water element and makes the mind dispassionate towards the water element.
16. “What, bhikkhu, is the fire element? The fire element may be either internal or external. What is the internal fire element? Whatever internally, belonging to oneself, is fire, fiery, and clung-to, that is, that by which one is warmed, ages, and is consumed, and that by which what is eaten, drunk, consumed, and tasted gets completely digested, or whatever else internally, belonging to oneself, is fire, fiery, and clung-to: this is called the internal fire element. Now both the internal fire element and the external fire element are simply fire 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 fire element and makes the mind dispassionate towards the fire element.
