成唯識論述記 6.614

6.614

述曰：第七、八識如前已說；意識並有；五識但三，以無分別故無慢等，慢等必由有隨念、計度分別生故。又由慢於稱量門起，方勝負故；疑，猶豫簡擇門起；見，推求門起，故非五識。故五識無此等行相，故《對法》第七說稱量等門，即等猶豫門等也。

The Commentary states: The seventh and eighth consciousnesses are as explained above. The mental consciousness has all of them. The five consciousnesses have only three, because having no discrimination, they lack pride and so forth; pride and the like necessarily arise only through having recollective and calculative discrimination. Furthermore, pride arises through the mode of weighing and measuring, comparing superiority and inferiority; doubt arises through the mode of vacillating discernment; and views arise through the mode of investigation; therefore they do not belong to the five consciousnesses. Thus the five consciousnesses lack these aspects of activity, and so Chapter Seven of the Abhidharma-samuccaya speaks of the mode of weighing and measuring, which refers to the mode of vacillation and so forth.
