首楞嚴義疏注經 5.120

5.120

上文云「若能於此悟圓通根，逆彼無始織妄業流，得循圓通，與不圓根日劫相倍。但汝下劣，未能於中圓自在慧，故我宣揚，令汝但於一門深入，入一無妄，彼六知根一時清淨。」故云選擇。下文云「見聞如幻翳，三界若空華，聞復翳根除，塵消覺圓淨。」是故諸妄消亡，不真何待。

The text above states: "If you can awaken to the faculty of perfect penetration here and reverse that beginningless flow of karmic fabrication, following perfect penetration, the difference between it and the non-perfect faculties will be like days compared to kalpas. But you are inferior and not yet able to attain the round, sovereign wisdom within it; therefore I explain it, so that you may enter deeply through a single gateway. Entering one without falsity, those six cognitive faculties will become pure all at once." Thus it says "choose". The text below states: "Seeing and hearing are like illusory cataracts; the three realms are like flowers in space. When hearing returns, the root of the cataract is removed; when dusts vanish, awakening is perfectly pure." Therefore, all delusions dissolve and vanish; what else could it be but the true?
