瑜伽論記 2.208

2.208

初中，彼宗緣無不生心，緣兔角等時，曾別見其兔，曾別見其角，合之一處，非今緣無。若爾，便與佛教相違，說無知無故；不爾，唯應有知其有。下難緣無覺者，是設遮計。

In the first part: That school holds that consciousness does not arise with non-existence as an object; when cognizing the horns of a hare and the like, one previously saw the hare separately and previously saw the horns separately, and combines them in one place, which is not presently taking non-existence as an object. If so, this would contradict the Buddha's teaching, because he spoke of "knowing non-existence when it is non-existent"; otherwise, one should only know existence when it exists. The subsequent challenge regarding awareness taking non-existence as an object hypothetically wards off their assertion.
