仁王護國般若經疏 5.69

5.69

「白佛言如是」下，第二正問。文二：先讚。不可以口說智解識識此法門也。「云何諸」下，二請也。空者即般若智慧也。由此智慧能得神通變化，一切眾生不知請佛開發也。

From "addressed the Buddha, saying: 'So it is'" onward is the second [part], the formal question. The text has two parts: first, praise: this Dharma gate cannot be known by verbal explanation, intellectual understanding, or cognitive consciousness; from "how do the..." onward, second, the request. Emptiness is prajñā wisdom. By means of this wisdom one can attain supernatural powers and transformations; because all sentient beings do not know this, he requests the Buddha to disclose it.
