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.
