金剛般若經疏論纂要 2.215

2.215

魏加後偈云「彼如來妙體，即法身諸佛，法身不可見，彼識不能知。」偈云「唯見色聞聲，是人不知佛，以真如法身，非是識境故。」無著云：「以彼法真如相故，非如言說而知，唯自證知故。」

The Wei [translation] adds the following verse: / 'That wondrous essence of the Tathāgata / is the dharmakāya of all Buddhas; / the dharmakāya cannot be seen, / and that consciousness cannot know it.' / The verse says: / 'Only seeing form and hearing sound, / this person does not know the Buddha, / because the dharmakāya of tathatā / is not an object of consciousness.' / Asaṅga says: 'Because it has the mark of the tathatā of dharmas, it is not known as spoken, but is only known through personal realization.'
