2.496

何況如說修行。斯人則為閉眾惡趣開諸善門。常為諸佛之所護念。降伏外學摧滅魔怨。修治菩提安處道場。履踐如來所行之跡　此二歎修行也。一念修行閉八難惡趣。開五乘善門行。應則諸佛宜護修。正則外魔摧伏隨順佛理。名修菩提不移。此心必安道樹無上佛果信心為本。萬行菩提一念為階。所以始於一念修行即是履踐如來所行之跡。

'How much more so if they practice as spoken! Such a person will close all evil destinies and open all gates of goodness; they will constantly be protected and remembered by the Buddhas, subdue non-Buddhist learners, destroy the foes of Māra, cultivate bodhi, abide peacefully in the bodhimaṇḍa, and tread in the footsteps of what the Tathāgata has walked.' This is second, praising practice. A single thought of practice closes the evil destinies of the eight difficulties and opens the gates of goodness of the five vehicles. If practice corresponds, it is fitting for the Buddhas to protect it; if cultivation is correct, external demons are subdued. Following the Buddha's principle is called cultivating bodhi; not wavering in this mind, one will surely rest peacefully beneath the bodhi tree. The supreme fruit of Buddhahood takes the mind of faith as its root; the myriad practices of bodhi take a single thought as their step. Therefore, beginning with a single thought of practice is itself treading in the footsteps of what the Tathāgata has walked.
