瑜伽論記 2.172

2.172

'Being different or not different': does the dharma possessing the nature of an effect in the cause differ or not differ from the effect manifested upon encountering conditions? If it does not differ, the dharma should be permanently manifest, because the original dharma was permanently existent beforehand; to say that it was manifest before and is manifest now does not accord with reason. The inference is: The effect in your school should have been manifest from the beginning, because it is identical to the original dharma; the inference that reverses this can be known by analogy.
