首楞嚴義疏注經 3.504

3.504

「阿難！汝心麁浮，不悟見聞發明了知本如來藏。汝應觀此六處識心，為同為異？為空為有？為非同異、為非空有？」

"Ānanda, your mind is coarse and superficial, and you do not realize that the discerning knowledge manifested from seeing and hearing is fundamentally the tathāgatagarbha. You should contemplate the conscious mind at these six locations: is it identical or different? Is it empty or existent? Is it neither identical nor different, neither empty nor existent?"
