首楞嚴義疏注經 1.666

1.666

結失也。不了性一切心，即是失真，此斥二乘不知常也。認物為己，此指凡夫以動為身等也。下文身之與心皆是真心中所現物，執為自己，顛倒斯甚。自體不識，妄取他緣，如懷至寶於外求匃，誰之過歟？故云自取流轉。

Concluding the loss. Failing to understand that nature is all mind is precisely losing reality; this reproaches the two vehicles for not knowing the permanent. Mistaking things for the self refers to ordinary persons taking what moves to be the body, and so on. In the text below, both body and mind are things manifested within the true mind; clinging to them as oneself is inversion at its extreme. Not recognizing one's own essence, one falsely grasps other conditions, like carrying an utmost treasure within one's bosom yet begging outside—whose fault is it? Thus it says: "bringing about one's own transmigration."
