sn35.127:3.1 “Great king, this has been stated by the Blessed One, who knows and sees, the perfected one, the fully awakened Buddha:
sn35.127:3.2 ‘Please, monks, examine your 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.
sn35.127:3.3 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.’
sn35.127:3.4 This is also a cause, Great King, this is a reason why these young monks live the full and pure spiritual life for their entire life, maintaining it for a long time.”
sn35.127:3.5 “This is easy to do for those mendicants who have developed their physical endurance, ethics, mind, and wisdom.
sn35.127:3.6 But it’s hard to do for those mendicants who have not developed their physical endurance, ethics, mind, and wisdom.
sn35.127:3.7 Sometimes I plan to focus on something as ugly, but only its beauty comes to mind.
sn35.127:3.8 Is there another cause, another reason why these young monks live the full and pure spiritual life for their entire life?”
