大方廣佛華嚴經隨疏演義鈔 37.24

37.24

疏「一離所取」者，謂二偈中，初一偈所取，即遍計所執也。「上半知於情有」者，即遍計中二義，謂情有、理無。今知情有即是理無，則知此性即無相也。

Regarding the Commentary's 'First, separating from the grasped object': among the two verses, the grasped object of the first verse is the imaginary [nature]. Regarding 'The upper half knows existence in emotion': these are two meanings within the imaginary, namely 'existence in emotion' and 'non-existence in principle'. Now knowing that existence in emotion is precisely non-existence in principle, one then knows that this nature is devoid of characteristics.
