是身如丘井為老所逼　丘井者故破村落。丘墟故井也。謂人物宮室移就新居。井不可改日見崩壞。人老亦然。盛力少色皆悉遷移衰老形骸留。此散壞此老壞想也。肇曰。神之處身為老死所逼。猶危人之在丘井為龍蛇所逼也。緣在他經。

"This body is like an abandoned well on a hill, pressed by old age." An 'abandoned well on a hill' refers to a ruined old village mound and its ancient well. When people and dwellings have moved to a new site, the well cannot be moved and is seen collapsing day by day. Human aging is also like this: vigor and youthful complexion completely depart, leaving behind only the declining, aged skeleton to disintegrate. This is the perception of aging and ruin. Sengzhao states: "The spirit dwelling in the body being pressed by old age and death is like a person in danger inside an abandoned well being pressed by dragons and serpents; the story is found in another sūtra."
