俱舍論記 29.119

29.119

「若爾意根至及自境界」者，犢子部難。言若五根取別境，不許取於我，第六意根境亦應別。六生喻契經中言：如是六根行處、境界各有差別，乃至自境界。此中意說：六生喻經六根行處、境界各別。理實意根兼能受用五根行處及彼境界，何妨前經五根行處、境界各別，而能兼取異根我境。經言五根取各別境，未是盡理之言。言六生喻經者，彼經說以繩繫鳥、蛇、猪、鼉、野干、彌猴，令不得隨意。鳥飛空中，喻眼根遠見。蛇多住穴，喻耳根在深孔內。猪受糞穢臭物，喻鼻著香。鼉樂水中，喻舌著味。味必因津液通之，舌方得味。野干樂住山林草庵，喻身著觸。彌猴性𮜒動不停，喻意多緣慮。以六眾生喻彼六根，名六生喻經。

Regarding "If so, then the mental faculty ... and its own objective field": the Vātsīputrīyas object. They say: if the five faculties grasp distinct objects and are not allowed to grasp the self, then the sixth faculty, the mental faculty, should also have a distinct object. In the *Sūtra on the Simile of the Six Animals*, it says: "Thus the scopes and objective fields of the six faculties each have their distinctions ... up to ... their own objective fields." What is meant here is: in the *Sūtra on the Simile of the Six Animals*, the scopes and objective fields of the six faculties are each distinct. In reality, the mental faculty also experiences the scopes and objective fields of the five faculties; what prevents the former sūtra's statement that the scopes and objective fields of the five faculties are each distinct from meaning that they can also grasp the self, the object of other faculties? When the sūtra says that the five faculties grasp distinct objects, it is not an exhaustive account of the truth. As for the *Sūtra on the Simile of the Six Animals*, that sūtra speaks of tying a bird, a snake, a pig, a crocodile, a jackal, and a monkey with a rope so that they cannot do as they please. The bird flies in the sky, illustrating the eye faculty seeing far. The snake mostly lives in holes, illustrating the ear faculty inside deep cavities. The pig takes pleasure in dung and foul odors, illustrating the nose attaching to smells. The crocodile delights in water, illustrating the tongue attaching to tastes. Taste must be conveyed by saliva before the tongue can experience taste. The jackal delights in dwelling in mountain forests and grass huts, illustrating the body attaching to tangibles. The monkey is by nature fickle and constantly moving, illustrating the mind having many discursive thoughts. Comparing the six faculties to six animals is why it is called the *Sūtra on the Simile of the Six Animals*.
