維摩經略疏垂裕記 4.165

4.165

二、「今不」下，據義懸釋，二：初、約四想。此四即十想中四也。一不淨想者，自他身內有三十六物，外則九孔惡露常流，從生至終無一淨也。二食不淨者，觀諸飲食不淨，皆從不淨因緣故有。三世間不可樂者，世間有二：一不見有好眾生、二不見有好國土。四死想者，死者常為死逐，出息不保入息。「是身為災」者，此約眾生世間。

Second, from "now not" downward, preliminarily explaining on the basis of the meaning, in two: first, in terms of the four perceptions. These four are four among the ten perceptions. First, the perception of impurity: within one's own and others' bodies there are thirty-six substances, and externally the nine apertures constantly flow with foul secretions; from birth to death not a single thing is pure. Second, the impurity of food: contemplating all drink and food as impure, all existing from impure causes and conditions. Third, the world being joyless: the world has two aspects: 1) not seeing good sentient beings, and 2) not seeing a good land. Fourth, the perception of death: death constantly pursues one; the outgoing breath cannot guarantee the incoming breath. Regarding "this body being a disaster," this is in terms of the world of sentient beings.
