44.67

疏「從婬欲生即種子不淨」者，疏中先說五種不淨：一種子不淨、二住處不淨、三自性不淨、四自相不淨、五究竟不淨，即《智論》二十一說，〈梵行品〉已廣其相。但自性不淨，即三十六物，今當更說。即《涅槃》十二〈聖行品〉云「從頭至足，其中唯有髮（一）、毛（二）、爪（三）、齒（四）、不淨（五）、垢穢（六）、皮（七）、肉（八）、筋（九）、骨（十）、脾（十一）、腎（十二）、心（十三）、肺（十四）、肝（十五）、膽（十六）、腸（十七）、胃（十八）、生藏（十九）、熟藏（二十）、大便（二十一）、小便（二十二）、涕（二十三）、唾（二十四）、目淚（二十五）、脂（二十六）、膏（二十七）、腦（二十八）、膜（二十九）、骨（三十）、髓（三十一）、膿（三十二）、血（三十三）、腦（三十四）、膀胱（三十五）、諸脈（三十六），菩薩如是專念時。」釋曰：遠公不分其中骨有二、腦有二、腦連膜，除二缺二，腸有大小亦缺其一，餘處有胞，具三十六。直就經文今具者。復有分垢為一、汗為一，則穢字屬汗，亦具三十六。

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.
