首楞嚴義疏注經 6.289

6.289

如前重睡心想不行，聞舂擣聲別作他物，此時豈憶靜搖？應知聞性不斷，故云不為不思無也。覺觀出思惟者，此既不與念想相應，即出覺觀思惟之表。譯人迴文不盡，故令語倒。覺觀，即尋伺也。思惟，即是遍行思也。俱是心所皆不相應，故名為出。又覺是本覺，即聞性也。觀即是照。此即文順。

As mentioned earlier, when in deep sleep mental thoughts do not operate, and upon hearing the sound of pounding mortars one mistakes it for something else, at that time does one recall stillness or movement? One should know that the nature of hearing is uninterrupted; hence it is said: 'It is not absent because one is not thinking.' 'Vitarka and vicāra transcend discursive thought' means that since this [nature of hearing] is not associated with mental thoughts, it transcends the sphere of vitarka, vicāra, and discursive thought. Because the translator did not fully rearrange the syntax, the phrasing became inverted. Vitarka and vicāra (jueguan) are vitarka (xun) and vicāra (si). Discursive thought is the omnipresent mental factor of volition (cetanā). All are mental factors that are not associated with it, hence it is said to 'transcend' them. Alternatively, 'jue' is original enlightenment (benjue), which is the nature of hearing; 'guan' is illumination. Read this way, the text flows smoothly.
