3.149

賢愚經云。比丘於十二入。思惟無量生死無常。又思惟地獄之苦。及。諸畜生更相殘害。餓鬼飢渴眾苦所逼。思惟人中四方馳求。天上敗壞。如是五道身心之苦。無有樂處。觀此五陰。無常苦空無我不實。譬如空村無有居民。如是五陰。皆空無我。以無常火燒諸世間。諸佛弟子常作此觀。云何得起一切煩惱。

The Damamūka-nidāna Sūtra says: 'The bhikṣu contemplates the impermanence of limitless saṃsāra in the twelve sense bases. He also contemplates the sufferings of the hells, as well as the animals mutually destroying each other, and the hungry ghosts oppressed by many sufferings of hunger and thirst. He contemplates humans rushing about in the four directions, and the decay in heaven. Thus the sufferings of body and mind in the five destinies have no place of joy. Contemplating these five aggregates as impermanent, suffering, empty, non-self, and unreal—just as an empty village has no inhabitants, so too these five aggregates are all empty and without self. With the fire of impermanence burning all the worlds, the disciples of the Buddhas constantly perform this contemplation; how could any defilement arise?'
