俱舍論記 13.18

13.18

「頌曰至俱表無表性」者，應知如是所說諸三業中，身、語二業俱表、無表性，同是色業。一能表示自心善等令他知故名表，一即不能表示自心故名無表，由斯差別，立二種名。意業非色，不能表示，故不名表，由無表故無表亦無，以無表名遮同色類身、語表示故。

[On the passage] "The verse says: […] Both are of the nature of vijñapti and avijñapti": One should know that among the three kinds of karma explained as such, the two karmas of body and speech are both of the nature of vijñapti and avijñapti, and are alike physical karma (rūpa-karma). One is named vijñapti (manifestation) because it can manifest one's own mind's wholesomeness and so forth, making it known to others; the other is named avijñapti (unmanifest) precisely because it cannot manifest one's own mind. In virtue of this distinction, two designations are established. Mental karma is not physical (rūpa) and cannot manifest [anything], hence it is not named vijñapti; and because there is no vijñapti, avijñapti is also absent [in it], for the name avijñapti [functions to] exclude the bodily and vocal manifestations that belong to the category of form (rūpa).
