首楞嚴義疏注經 5.105

5.105

心性發狂，見聞妄隔，根境識三一時俱現。生死為六，涅槃名一，由對待成，本無所有，故如狂勞虛妄華相。三種世間故名一切，佛界、生界、一切境界俱不離此，以是分別妄念起故，離心即無六塵境故。

When the mind-nature goes wild, seeing and hearing are falsely separated, and the three—faculties, objects, and consciousnesses—all appear simultaneously. Birth-and-death is designated as the six; nirvāṇa is called the one. Established through mutual opposition, they originally have no existence, and are therefore like the phantom imagery of flowers born of frantic strain. Because of the three kinds of worlds, it is called 'all'; the realm of the buddhas, the realm of sentient beings, and all realms whatsoever do not depart from this, because they arise from discriminative, false thoughts, and because apart from the mind there are no realms of the six dusts.
