瑜伽論記 2.169

2.169

量云：汝宗之果，應永不顯，常有性故，猶如未顯，汝宗因體，亦應為障，體常有故，猶如於果。

The inference is: The effect in your school should never be manifested, because it permanently has existence-nature, like [when it is] unmanifest; the entity of the cause in your school should also act as an obstruction, because its entity is permanently existent, like the effect.
