俱舍論記 1.217

1.217

「頌曰至各生二處」者，釋。端嚴有兩解：初解令身端嚴，此解有過。第二解令識端嚴，此解無妨。舌、身形大，發識用足，故不須二。又《婆沙》十三云「問：何故眼、耳、鼻各有二處，而舌、身唯一耶？答：諸色根處為莊嚴身。若有二舌，是鄙陋事，世便蚩咲：云何此人若有二舌，如似毒蛇。若有二身，亦是鄙陋，世所蚩咲：云何一人而有二身，如兩指竝。

"The verse says ... each arises in two locations": the explanation. "Well-proportioned" (śobha) has two explanations: the first explanation is to make the body well-proportioned, which has a flaw. The second explanation is to make the consciousness well-proportioned, which is unproblematic. The tongue and body are large in form and their function in generating consciousness is sufficient, so two are not needed. Furthermore, the *Mahāvibhāṣā*, fascicle 13, says: "Question: Why do the eye, ear, and nose each have two locations, while the tongue and body have only one? Answer: The locations of the material sense-bases are for beautifying the body. If there were two tongues, that would be ugly, and the world would ridicule it: 'Why does this person have two tongues, like a venomous snake?' If there were two bodies, that would also be ugly, and ridiculed by the world: 'Why does one person have two bodies, like two fingers side by side?'"
