法華義疏 6.95

6.95

「雜穢充遍」者，第三、明不淨觀也。有人言：從「有一大宅」至「而復頓弊」，總序三界無常也。從「堂舍高危」以下，別序五陰四大無常也。「堂舍」者總明五陰是眾生所栖，是故經云「五陰舍宅觀悉空寂」；「柱根」以下別明五陰無常也。色陰中地大能持故為柱，柱分分不實如摧朽也。識陰為一身之主是梁棟，識無定主如幻為傾科；行陰是一身之本為基陛，一起一滅為頹毀；亂想周障取像而不實為牆壁圮坼；三受互起不住如埿塗褫落，此序五陰無常竟。「覆苫亂墜」下，別明四大無常也。風大能傾覆為覆苫亂墜，椽梠不能相持，似堅而非堅，譬地大之不實也。「周障屈曲」，如火大遍在一形之中，隨身老壯火有強弱不得自在也。「雜穢充遍」者，六根膿血渧唾不淨，譬水大也。

"Full of various filths" is the third, elucidating the contemplation of impurity. Some say: from "There was a great house" to "and all at once ruined and collapsed" is a general narration of the impermanence of the three realms. From "The halls and chambers were lofty and precarious" downward, it separately narrates the impermanence of the five aggregates and four great elements. "Halls and chambers" generally elucidates that the five aggregates are where sentient beings dwell, and therefore the sūtra states, "Observing the house of the five aggregates, all is completely empty and quiescent." From "The bases of the pillars" downward, it separately explains the impermanence of the five aggregates. In the aggregate of form, the earth element can support, hence it is the pillars; the pillars are insubstantial part by part, like crumbling decay. The aggregate of consciousness is the master of the whole body, which is the beams and ridgepoles; consciousness has no fixed master and is like an illusion, hence being leaning and slanted. The aggregate of formations is the root of the whole body, which is the foundations and steps; rising at one moment and perishing at another, it is collapsed and ruined. Scattered thoughts surround and barrier, grasping forms without reality, which is the walls collapsing and fracturing. The three feelings arise reciprocally without abiding, like plaster peeling away. This finishes the narration of the impermanence of the five aggregates. From "The thatched thatch disorderly fell" downward, it separately explains the impermanence of the four great elements. The wind element can overturn, which is the thatched thatch disorderly falling; the rafters and eaves cannot support one another, seemingly solid yet not solid, which illustrates the unreality of the earth element. "The surrounding barriers were bent and curved": like the fire element pervading throughout the single form, the fire has strength or weakness according to the body being old or robust, lacking self-mastery. "Full of various filths": the pus, blood, dripping, and saliva of the six sense faculties are impure, which illustrates the water element.
