非已思應思現量者，已思應思多是比量，或非量攝，今非此二故名現量，纔取便成取所依境者乃至其病若愈，名為已思等，景云：四塵實法病人四識，纔取則得成境，非已思應思故是量，藥有除病功能，病人意識思量，此藥今療我疾已愈未愈，是其比量。

Regarding "direct perception that is not already thought of or to be thought of": what has already been thought of or is to be thought of mostly belongs to inference (anumāna) or is subsumed under non-valid cognition (apramāṇa); now, not being these two, it is called direct perception. Regarding "the moment it is apprehended it is immediately accomplished, apprehending the foundational object... up to if the illness is cured, it is called already thought of, and so forth": Jing says: The real dharmas of the four dusts are apprehended by the patient's four consciousnesses, and the moment they are apprehended they immediately constitute objects; because they are neither already thought of nor to be thought of, they are valid cognition. A medicine has the efficacy to remove illness; the patient's mental consciousness deliberates: "This medicine is now treating my sickness; is it cured or not yet cured?" This is inference.
