7.80

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.
