大般涅槃經義記 5.65

5.65

觀中有六：一明菩薩畏死捨生；二童子喻，辯明菩薩不同近行求生斷死；三賣食喻，不同凡夫為生造因；四毒樹喻，明死苦寬遍，成生可厭；五糞穢喻，明死苦寬長，成生可厭；六嶮岸喻，明生雜妄樂令人貪惑，成生可畏。

Within the contemplation, there are six [parts]: first, explaining that the bodhisattva fears death and renounces birth; second, the parable of the boy, clarifying that the bodhisattva is not like the novice who seeks birth to sever death; third, the parable of selling food, [showing that he is] not like the ordinary person who creates causes for the sake of birth; fourth, the parable of the poisonous tree, explaining that the suffering of death is pervasive and widespread, establishing that birth is to be loathed; fifth, the parable of excrement, explaining that the suffering of death is vast and enduring, establishing that birth is to be loathed; sixth, the parable of the precipitous cliff, explaining that birth is intermingled with false pleasures that cause people to be greedily deluded, establishing that birth is to be feared.
