首楞嚴義疏注經 2.427

2.427

求法空智，名施大惠目。見實相理，名覺心明淨。此明真見離緣絕相，言思不及，非二乘境界，故增迷悶。不承決擇，孰能通曉，故垂淚禮請也。

Seeking the wisdom of the emptiness of phenomena is called 'bestowing the great eye of wisdom.' Seeing the principle of the real mark is called 'the clear purity of the awakened mind.' This explains that true seeing is separated from conditions and beyond marks, inaccessible to speech and thought, and not the domain of the two vehicles; therefore bewilderment redoubled. Without receiving [the Buddha's] resolution, who could comprehend it? Thus, shedding tears, he prostrated and petitioned.
