仁王護國般若經疏 5.11

5.11

「是以般若」下，二結上四義。文即為四：「不可眾生中行」，結人空。「不可法中行」，結法空。「不可境中行」，結境空。「不可解中行」，結智空也。

From "therefore, prajñā" below, second is concluding the above four meanings. The text has four parts: "cannot be practiced among sentient beings" concludes the emptiness of persons; "cannot be practiced among phenomena" concludes the emptiness of phenomena; "cannot be practiced in the object" concludes the emptiness of the object; "cannot be practiced in understanding" concludes the emptiness of wisdom.
