金剛般若波羅蜜經註解 1.248

1.248

所說法，蓋佛離言說相，以離相故，能作菩提之因，故慈氏偈云：「雖言無記法。而說是彼因。」彼即菩提也。

As for the Dharma taught, the Buddha is detached from the mark of verbal expression; because he is detached from marks, it can serve as the cause of bodhi. Therefore Maitreya's verse states: / Although spoken of as an unspecified dharma, / it is taught to be the cause of that. / "That" refers to bodhi.
