釋禪波羅蜜次第法門 2.135

2.135

今釋六法，自可為二意：一、約果明；二約因明。先約欲界果明，言「厭下苦、麁、障」者，厭患欲界底下色心麁重故。行者思惟：今感欲界報身，饑渴、寒熱、病痛、刀杖等種種所逼，故名苦。麁者，此身為三十六物屎尿臭穢之所成，故名為麁。麁者，醜陋故。障者，此身質礙，不得自在，為山河石壁所隔礙，故名為障。

Now, in explaining the six dharmas, there are naturally two perspectives: first, explaining in terms of the result; second, explaining in terms of the cause. First, explaining in terms of the result in the desire realm: as for the phrase 'reviling the lower as suffering, coarse, and obstructive', it is because one is disgusted with the coarse and heavy form and mind of the lowest desire realm. The practitioner contemplates: 'Now receiving a retributive body in the desire realm, I am pressed by hunger, thirst, cold, heat, illness, pain, knives, clubs, and so forth; hence it is called suffering.' 'Coarse': this body is composed of thirty-six foul things such as feces and urine; hence it is called coarse. 'Coarse' means ugly and loathsome. 'Obstructive': this body is material and impeded, lacking freedom, obstructed by mountains, rivers, rocks, and walls; hence it is called obstructive.
