太子瑞應本起經 1.30

1.30

「於是太子，攀樹枝見耕者，墾壤出虫，烏隨啄吞，感傷眾生，魚鱗相咀，其不仁者，為害滋甚，死墮惡道，求出良難。諸天雖樂，而亦非常，福盡則懼，罪至亦怖，禍福相承，生死彌久。觀見人間，上至二十八天，貴極而無道，皆與地獄對門。三惡道處，痛酷百端，歡樂暫有，憂畏延長。天地之間，無一可奇，吾不能復為欲惑矣。

"Thereupon, the Prince took hold of a tree branch and saw plowers turning up the soil, bringing out insects, and crows following behind to peck at and swallow them. Pained with grief for sentient beings, like fish gnawing on each other's scales, [he saw that] the merciless cause ever greater harm, and upon dying fall into the evil destinies, finding escape exceedingly difficult. Although the devas enjoy bliss, it too is impermanent: when merit is exhausted they feel dread, and when retribution arrives they are terrified; misfortune and fortune follow one another, and their saṃsāra is exceedingly long. Observing the human world up to the twenty-eighth heaven, though one's nobility may be supreme, if one lacks the Way, one stands face to face with the gates of hell. In the three evil destinies, the bitter pain is of a hundred kinds; joy and pleasure are momentary, but anxiety and dread are prolonged. Between heaven and earth, there is nothing admirable; I can no longer be deluded by desire."
