首楞嚴義疏注經 3.7

3.7

借前色陰中見華瞪目以為喻也。目睛喻覺性，瞪發勞喻妄念忽生。兼目與勞等，即此眼根能結所結，起不離真，故云同是菩提。經文語略，若細論之，即淨目喻覺性，因瞪發勞喻無明不了故成念動，由發勞故見空中華，喻由念動故現妄境界及根身等。兼目與勞下，約喻指法也。目即無明動，心勞即所現根境及能見心，此之心境及與動念，俱是菩提性中無明勞相，無體可得，虛妄發生，猶如瞪目見空中華，俱為勞也。

This borrows the staring eye that sees flowers from the previous section on the aggregate of form as an analogy. The eyeball analogizes the nature of awareness; staring fixedly to produce fatigue analogizes the sudden arising of delusive thoughts. "Both the eye and the fatigue," etc., refers to this eye faculty's grasping subject and grasped object arising without departing from the real, hence it says "are together bodhi." The sūtra text is brief; if discussed in detail, the clear eye analogizes the nature of awareness; producing fatigue due to fixed staring analogizes the movement of thoughts forming because of the failure to comprehend avidyā; seeing flowers in space due to producing fatigue analogizes the manifestation of delusive realms and the physical faculties and bodies due to the movement of thoughts. From "Both the eye and the fatigue" downward, the teaching is pointed out based on the analogy. The eye is the movement of avidyā; mental fatigue is the manifested faculties and objects as well as the observing mind; both this mind and objects, along with the moving thoughts, are entirely marks of fatigue born of avidyā within the nature of bodhi, having no substance to be found and arising falsely, just like the staring eye seeing flowers in space—all are fatigue.
