The answer says: “The substance of wisdom is non-dual, and the object is also non-dual. That wisdom is non-dual means it is just one single wisdom, but distinct in meaning and function: in terms of knowing the ultimate, it is named ultimate wisdom; in terms of knowing the conventional, it is named conventional wisdom. That the object is non-dual means form is emptiness is the ultimate object, and emptiness is form is the conventional object. Hence, when realizing the ultimate, one must penetrate the conventional; when penetrating the conventional, one must realize the ultimate. Understanding that the conventional lacks self-nature is precisely true emptiness; how could there be before and after? Furthermore, since there is no object outside the mind, how could there be a mind outside the object? Thus mind and object are completely fused, constituting one single dharmadhātu.”
