成唯識論述記 9.115

9.115

述曰：第二難也。若有漏二分皆是計所執者，應非所緣緣，彼言計所執許二非有故，如兔角等。彼計二分非所緣緣，所緣緣者，陳那破他就他為論，我既唯識，何藉緣生？

The Commentary states: The second objection. If the two sāsrava parts were both the imagined nature, they should not be the ālambanapratyaya (objective condition), because that [master] asserts that the imagined lacks both [parts], just like rabbit horns and the like. He asserts that the two parts are not the objective condition. Regarding the objective condition, Dignāga refuted the other [tradition] by arguing based on their position: since our system is vijñapti-mātra, why rely on arising from conditions?
