成唯識論了義燈 7.80

7.80

答：望義有別。照所取無，名之為明；推求所取假有實無，名為尋思。故《無性論》云：「於加行時，推求行見假有實無，方便因相說名尋思。」下文「明謂能照無有義智」，言「定」舉照義，明觀舉推求，互舉無妨。

Answer: Looked at from different perspectives, their meanings differ. Illuminating the nonexistence of the grasped object is termed "light"; inquiring into the grasped object as nominally existent but substantially nonexistent is termed "investigation." Thus, the commentary of Asamāhita says: "At the time of preparation, inquiring into and seeing through practice that things are nominally existent and substantially nonexistent: this sign of expedient causation is termed investigation." In the passage below, "light refers to the wisdom capable of illuminating the absence of external objects"; the word "samādhi" highlights the sense of illumination, while "light contemplation" highlights inquiring. Highlighting either one presents no contradiction.
