首楞嚴義疏注經 1.467

1.467

正顯也。眾生受身，輪迴五道，莫窮初際，故云無始。聚緣內搖，趣外奔逸，故曰攀緣。造善惡因，受苦樂報，死此生彼，皆因此心，故云根本。不了是妄，一迷為心，決定惑為色身之內，故云為自性者。吁哉！世人莫不用此攀緣妄心以為真性，執妄心為佛心，恃此修行，轉增我慢。《涅槃經》云「是諸外道，無有一法不從緣生，計為常者悉是顛倒。」

This directly reveals it. Sentient beings receive bodies and transmigrate in the five destinies, unable to fathom the initial limit, hence it says "beginningless." Gathering conditions and stirring within, rushing and running toward the external, is therefore called "climbing upon conditions." Creating good and evil causes, experiencing bitter and sweet retributions, dying here and being born there—all are due to this mind, hence called the "root." Failing to understand that it is false, once deluded into taking it as the mind, they are determinedly confused into thinking it is within the physical body, hence it says "take as your self-nature." Alas! There is no worldly person who does not take this climbing, false mind as their true nature, grasping the false mind as the Buddha-mind, relying on this to cultivate, thereby increasing their arrogance even more. The *Nirvāṇa Sūtra* says: "Among these non-Buddhists, there is not a single dharma that does not arise from conditions; considering them permanent is entirely an inversion."
