四、空空。空空者，以空破內外空。內外空破是三空，故名為空空也。故《維摩經》云：「得此法已，無有餘病，唯有空病。」空病亦空，故名空空。

Fourth: emptiness of emptiness. Emptiness of emptiness means using emptiness to dismantle internal and external emptiness. The dismantling of internal and external emptiness is these three emptinesses, therefore it is called emptiness of emptiness. Thus the Vimalakīrti-sūtra says: 'Having attained this Dharma, there is no other illness, only the illness of emptiness.' The illness of emptiness is also empty, hence it is called emptiness of emptiness.
