華嚴經探玄記 20.37

20.37

第七幻智光明門知識內，初中妙月者，悲德清涼，故以為名。上文云「菩薩清涼月，遊於畢竟空」，此之謂也。宅有光明，是法門之用。四示己法界中標名，內證離障為淨智，後智攝物故曰光明。又光明者，對治無明故。淨者，治惑染故。餘文可知。

Within the seventh spiritual friend of the gate of radiant illusory wisdom: in the first, "Wondrous Moon" is so named because the cooling nature of the virtue of compassion. As the text above says, "The bodhisattva's cooling moon / wanders in the ultimate emptiness"—this is what is meant. The radiance present in the residence is the function of the Dharma-door. In the fourth, revealing his own dharmadhātu, the name is indicated: the inner realization being free from hindrances is "pure wisdom"; subsequent wisdom gathering in beings is called "radiance." Furthermore, "radiance" is because it counteracts fundamental ignorance. "Pure" is because it counteracts the defilement of delusion. The rest of the text can be understood.
