首楞嚴義疏注經 4.240

4.240

汝與眾生，合前琴等。寶覺真心，合前妙音。按指，約喻指法，即無生智，合無相理，大用現前，即前云「我以不滅不生合如來藏，而如來藏唯妙覺明，圓照法界，乃至於中一為無量」等。汝暫舉心等，合前無妙指也，即前云「汝以色空相傾相奪於如來藏，而如來藏隨為色空」等。言海印者，《大集經》云「閻浮所有色像，大海皆有印文，喻佛如來法身性海，普現一切妙用之光也。」

'You and sentient beings' matches the zither and so on above. 'The precious, awakening, true mind' matches the wondrous sounds above. 'Pressing my finger' refers to the simile pointing to the doctrine, which is the wisdom of non-arising matching the unconditioned principle, where the great function appears before one; this corresponds to what was said earlier: 'With non-extinction and non-arising I accord with the tathāgatagarbha, and the tathāgatagarbha is solely wondrous awakening and brightness, completely illuminating the dharmadhātu... and within it, one is immeasurable,' and so forth. 'As soon as you raise a thought,' and so forth, matches having no wondrous fingers above; this corresponds to what was said earlier: 'With form and emptiness you contend and usurp within the tathāgatagarbha, and the tathāgatagarbha accordingly becomes form and emptiness,' and so forth. Regarding the 'ocean-seal', the Mahāsaṃnipāta Sūtra states: 'Whatever forms and images there are in Jambudvīpa, the great ocean has seal-impressions of them all; this is a simile for the Buddha Tathāgata's ocean of Dharmakāya nature universally displaying the light of all wondrous functions.'
