俱舍論疏 22.118

22.118

論「又契經說至說有取識」，釋五種子。有二釋。第一釋云：一根、二莖、三枝、四節、五子。喻有取識。第二釋云：五種子者，謂五趣種子說有取識，取是煩惱，有煩惱識為五趣因，名有取識。既契經中不言喻說，後釋為正。此證經中非唯說愛。

On the Śāstra's 'Furthermore, a sūtra states [...] consciousness with grasping is spoken of': Explaining the five seeds. There are two explanations. The first explanation states: first, roots; second, stems; third, branches; fourth, joints; fifth, seeds. These are similes for consciousness with grasping. The second explanation states: the 'five seeds' means that the seeds of the five destinies are called consciousness with grasping; 'grasping' is affliction, and consciousness accompanied by affliction is the cause of the five destinies, hence called consciousness with grasping. Since the sūtra does not state this metaphorically, the latter explanation is correct. This proves that the sūtra does not speak of craving alone.
