瑜伽論記 21.106

21.106

泰法師云：第一句立因不成，如立宗云總蘊是無常，因言意識所識故，然無為同是意所識法非無常故。第二句，如立宗云聲是無常，因云耳識所聞故，然色香等異類法非耳識所聞。然是無常故，立因不成，若立宗云聲是常，因云從因生故。然更無有異類不取因生法是無常故，異類不可得。

Master Tai says: In the first phrase, establishing the reason is unproven (asiddha). For example, establishing the thesis, "The aggregate as a whole is impermanent," with the reason, "Because of being cognised by the mental consciousness." However, the unconditioned is equally a dharma cognised by the mind, yet is not impermanent. In the second phrase, for example, establishing the thesis, "Sound is impermanent," with the reason, "Because of being heard by the ear consciousness." However, different classes of dharmas such as form and scent are not heard by the ear consciousness; yet they are impermanent, so establishing the reason is unproven. If one establishes the thesis, "Sound is eternal," with the reason, "Because of being born from causes"—yet there are no different classes of dharmas not born from causes that are impermanent, so the different class cannot be obtained.
