金剛般若經贊述 2.124

2.124

無著釋云，不可如言而取，故不實；亦非離言以求，故不虛。凡夫言而虛妄，故不實；諸佛說而可依，故不虛。凡夫言不得，故不實；寄佛語而可詮，故不虛也。若離言而有求，即菩提無因，名為不實；要因聞教方得證，故菩提有因，名為不虛。若如言而取著，生死無出，故不可如言；即稱法必因言，方契真也。但順佛言而修，後證會時自悟。

Asaṅga explains: It cannot be grasped according to literal expression, hence 'not real'; nor is it sought apart from words, hence 'not unreal.' What ordinary beings say is false, hence 'not real'; what the Buddhas preach can be relied upon, hence 'not unreal.' Ordinary beings cannot attain it through speech, hence 'not real'; it can be expressed by resorting to the Buddha's words, hence 'not unreal.' If one seeks it apart from words, bodhi would be without a cause, which is called 'not real'; but because it must depend on hearing the teaching before it can be realized, bodhi has a cause, which is called 'not unreal.' If one grasps and clings according to literal expression, there is no escape from saṃsāra, and thus one must not [grasp it] according to literal expression; yet matching the Dharma necessarily depends on words, and only then accords with the real. One need only cultivate in accordance with the Buddha's words, and later, at the time of realization and joining, one will awaken on one's own.
