說無垢稱經疏 6.554

6.554

贊曰：四如來重勸。欲外成淨土，內身為菩薩，應學彼佛本菩薩行。即諸經言「度脫諸眾生，即生不動國」，等一切勝行。

Commentary: (4) The Tathāgata reiterates his encouragement. If one wishes to accomplish a pure land externally, and inwardly become a bodhisattva, one should emulate that Buddha's original bodhisattva practices. This is what various sūtras say: "Liberating all sentient beings, one will be born in the land of Akṣobhya," and all such supreme practices.
