佛說處處經 1.26

1.26

「佛、辟支佛、阿羅漢是三人，法同行異：佛者為覺意；辟支佛為見因緣知；阿羅漢坐禪乃知。辟支佛為因緣見生死相，自守不敢離行，從見因緣得道，故為辟支佛。佛者為通行欲度脫人故，故求辟支佛。辟支佛自割身活五百人，以木自刺其頸見因緣計挍，如割土見血是水、見萬物皆非常，便取道。有辟支佛，先世為菩薩五百劫，身已有三十相，無二相不及佛，不及佛者，無善權方便故。

"The Buddha, the pratyekabuddha, and the arhat—these three persons—are identical in the Dharma but differ in their practices: the Buddha is awakened in mind; the pratyekabuddha knows by seeing nidānas; the arhat only knows through seated meditation. The pratyekabuddha, through nidānas, sees the characteristics of birth and death, guards himself, and dares not depart from practice; because he attains the Way from seeing nidānas, he is called a pratyekabuddha. The Buddha sought the pratyekabuddha [path] for the sake of comprehensive practice and wishing to deliver and liberate people. A pratyekabuddha cut his own flesh to keep five hundred people alive, and pierced his own throat with wood; examining and calculating through nidānas, just as cutting the earth reveals blood to be water, and seeing that all things are impermanent, he then took the Way. There was a pratyekabuddha who in a past life was a bodhisattva for five hundred kalpas, and his body already possessed thirty marks, lacking two marks and falling short of the Buddha; falling short of the Buddha was because he lacked skillful means.
