10.147

又智度論云。身精進為少。心精進為大。外精進為少。內精進為大。復次佛說。意業力大故。如仙人瞋時。能令大國磨滅。復次身口作五逆罪。大果報一劫在阿鼻地獄。受意業力。得生非有想非無想處。壽八萬大劫亦在十方佛國。壽命無量。以是故。身口精進為少。意精進為大。如是諸經廣歎精進。一心正念速得道果。未必要須多聞。又毘婆沙論云。如二人俱至一方。一乘疾馬。一乘鈍馬。雖乘鈍馬。以前發故先有所至。信解脫人。勤行精進先至涅槃。即是周利等也。

Furthermore, the *Mahāprajñāpāramitopadeśa* states: "Bodily vigor is lesser; mental vigor is greater. External vigor is lesser; internal vigor is greater. Moreover, the Buddha taught that the power of mental karma is great, just as when a ṛṣi becomes angry, he can cause a great country to be obliterated. Moreover, for committing the five inexpiable offenses with body and speech, the great retribution is one kalpa in the Avīci Hell; whereas through the power of mental karma, one can be born in the realm of neither-perception-nor-non-perception, with a lifespan of eighty thousand great kalpas, and also in the Buddha-lands of the ten directions, with an immeasurable lifespan. For this reason, the vigor of body and speech is lesser, while the vigor of mind is greater." In this manner, various sūtras extensively praise vigor; with single-minded correct mindfulness one quickly attains the fruits of the Way, without necessarily requiring broad learning. Furthermore, the *Vibhāṣā-śāstra* states: "It is like two men traveling together to a certain region: one rides a swift horse and one rides a slow horse. Although the latter rides a slow horse, because he set out earlier, he arrives first. A person who is liberated through faith, by diligently practicing vigor, arrives first at nirvāṇa—just like Panthaka and the others."
