首楞嚴義疏注經 4.133

4.133

The wondrous body of enlightened brightness originally possesses a clearly knowing nature, which is the wondrous brightness of the nature's enlightenment. Because of original clarity, in delusion it becomes an objectified mark, which is "establishing an object because of brightness"; hence it says "through clarity, marks are produced." These objectified marks are due to deluded discrimination; hence it says "arise from deluded seeing." This summarizes the preceding three kinds of continuity: all are due to delusion about original true brightness, falsely forming objectified marks; the object must produce the subject, gradually becoming coarse and prominent, thereupon forming the worlds, sentient beings, and karmic fruits, successively shifting and flowing; none of which departs from a single thought of avidyā's deluded awareness.
