首楞嚴義疏注經 5.293

5.293

心聞即耳識發明也。從於耳識得真圓通，入法界理，生滅識滅，寂滅現前，境智相冥，一體無二，還於心聞起用，分別眾生知見，可發明者即現其身。

'Mental hearing' is the ear-consciousness shining forth. From the ear-consciousness, he attained true perfect penetration and entered the principle of the dharmadhātu; the consciousness of arising and ceasing was extinguished, tranquil extinction became manifest, and realm and wisdom merged as one essence without duality. Turning back to use mental hearing to give rise to function, he distinguishes the knowledge and vision of sentient beings, and to those who can be enlightened, he manifests his body.
