俱舍論疏 11.68

11.68

論「此中有情至以立其名」，釋立名所以。前二、後三隨身變立名，第三、四、五從聲變立名也。

The treatise says: "The sentient beings here... establish their names based on this." This explains the reason for establishing the names. The first two and the last three are named according to bodily transformations; the third, fourth, and fifth are named according to vocal changes.
