俱舍論頌疏論本 1.149

1.149

釋曰：然為令端嚴者，論有二解。第一師解：為所依身相端嚴故，界體雖一，而兩處生。若眼、耳根處唯生一，鼻無二穴，身不端嚴。此釋不然，論主破云：若本來爾，誰言醜陋？又猫鵄等有何端嚴？第二正解：為所發識明了端嚴，現見世間，閉一目等了別色等便不分明，是故三根各生二處。

The commentary explains: 'Yet to make [the body] graceful': the treatise provides two explanations. The first master explains: in order that the appearance of the supporting body be graceful, though the entity of the dhātu is one, they arise in two locations. If the eye and ear sense bases were each to arise as only one, and the nose had no two nostrils, the body would not be graceful. This explanation is not correct; the author of the treatise refutes it, saying: 'If it were originally like that, who would say it is ugly? Moreover, what gracefulness do cats, owls, and the like possess?' The second, correct explanation: in order that the generated consciousness be clear and graceful. In the world it is observed that when one closes one eye or the like, the discernment of form and so on is not distinct; therefore, the three sense faculties each arise in two locations.
