首楞嚴義疏注經 6.179

6.179

此顯一真性海，離名絕相，非真非妄，不悟不迷，唯一圓常，餘無所得，即下妙性圓明，離諸名相，本來無有世界、眾生也。覺性周遍，甚深湛然，故如海也。下句重歎，不可思議，絕諸對待，故曰妙也。

This reveals the ocean of the single true nature, free from names and beyond marks, neither true nor false, neither awakening nor delusion, uniquely perfect and eternal, with nothing else to be found; this corresponds to the text below: “The wondrous nature is perfectly luminous, free from all names and marks; originally there are no worlds or sentient beings.” The nature of enlightenment is all-pervading, profoundly deep and serene, and therefore like an ocean. The second line reiterates praise for its inconceivability, beyond all dualities, and hence it is called “wondrous.”
