10.314

前四句躡前色陰動身之想，即明受陰是妄想也。由因下正顯也，因想梅等便有受領，若非領納焉得水生？此受亦是妄想轉變，妄生領納也。二驅馳者，領此順、違生苦、樂法，遂成損、益，為彼所使。照境而領，虛通無礙，故曰虛明。

The first four lines follow upon the previous thought moving the body in the aggregate of form, showing that the aggregate of feeling is false imagination. From 'This sourness...' onwards, it directly explains it: because of thinking of plums and the like, there is reception; if there were no taking in and reception, how could saliva be produced? This feeling is also the transformation of false imagination, falsely generating reception. As for 'driven by the two': receiving these agreeable and disagreeable [states] produces suffering and pleasure dharmas, which turn into harm and benefit, and one is driven by them. Illuminating the realm and receiving it, it is empty, penetrative, and unobstructed; therefore it is called 'falsely luminous.'
