成唯識論了義燈 6.146

6.146

答：略有三解：一云，彼許兔角非因生，故非所緣緣；二、分因生成所緣緣。今此據無，同彼兔角，故得為難；一云，本計雖無親所緣緣，心亦得生，以立唯識故。然陳那所說無非所緣緣者，是破他計就他為語，今者護法約自破彼，故為此量。

Answer: There are briefly three explanations: One says: He accepts that a rabbit's horn does not arise from causes, and therefore is not an objective condition; the two parts arise from causes and become objective conditions. Here, based on [their being] nonexistent, they are equated with that rabbit's horn, and so the objection can be made. One says: In the original doctrine, although there is no immediate objective condition, the mind can still arise, because consciousness-only is established. However, when Dignāga said that what is nonexistent is not an objective condition, that was refuting another's doctrine by speaking according to the other; now Dharmapāla refutes him according to his own [system], and therefore formulates this syllogism.
