諸經要集 3.79

3.79

第九念身者。謂專精念身。髮毛爪齒皮肉筋骨膽肝肺心脾腎大腸小腸。曲直旁光屎尿百葉。滄蕩脾泡溺淚唾涕。膿血脂涎髑髏腦等。何者是身。地種水種火種風種是也。皆是父母所造。從何處來。為誰所造。此之六根於此終已當生何處。除諸亂想自致涅槃。不離身念便獲功德。是名念身。

Ninth, mindfulness of the body: this means one with concentrated diligence is mindful of the body: hair, body hair, nails, teeth, skin, flesh, sinews, bones, gall, liver, lungs, heart, spleen, kidneys, large intestine, small intestine, the curved and straight [entrails], the bladder, feces, urine, omentum, stomach contents, spleen fluid, bubbles, urine, tears, saliva, nasal mucus, pus, blood, fat, drool, skull, brain, and so forth. What is this body? It is the earth element, water element, fire element, and wind element; it is entirely made by father and mother. Whence did it come? By whom was it made? When these six sense faculties perish here, where will they be born? Eliminating all turbulent thoughts, one personally attains nirvāṇa. Not departing from mindfulness of the body, one then obtains merit. This is called mindfulness of the body.
