大方廣佛華嚴經隨疏演義鈔 44.67

44.67

Regarding the commentary's statement, "Arising from sexual desire, it is impurity of the seed": the commentary first explains five kinds of impurity: first, impurity of the seed; second, impurity of the dwelling place; third, impurity of intrinsic nature; fourth, impurity of specific characteristic; fifth, ultimate impurity. This is stated in fascicle 21 of the *Mahāprajñāpāramitopadeśa*, and its characteristics have already been broadly explained in the "Chapter on Pure Conduct." But the impurity of intrinsic nature consists of the thirty-six substances, which will now be stated again. This corresponds to fascicle 12, the "Chapter on Holy Conduct" of the *Nirvāṇa Sūtra*, which states: "From head to foot, therein are only: hair of the head (1), hair of the body (2), nails (3), teeth (4), impurity (5), dirt and grime (6), skin (7), flesh (8), sinews (9), bones (10), spleen (11), kidneys (12), heart (13), lungs (14), liver (15), gallbladder (16), intestines (17), stomach (18), fresh food receptacle (19), digested food receptacle (20), feces (21), urine (22), nasal mucus (23), saliva (24), tears (25), fat (26), grease (27), brain (28), membranes (29), bones (30), marrow (31), pus (32), blood (33), brain (34), bladder (35), and the various vessels (36)—when the bodhisattva concentrates their mindfulness in this way." In explanation: Master Huiyuan does not distinguish the repetition where bones appear twice and brain appears twice, brain being connected to membrane; dropping two and lacking two, while intestines have large and small and also lack one, and elsewhere there is the placenta—[yet still] completing thirty-six. Directly following the sūtra text, it is now complete. There is also the division of dirt as one and sweat as one, so that the character *hui* (grime) belongs to sweat, which likewise completes thirty-six.
