華嚴經義海百門 1.63

1.63

初、顯光明者，謂見塵中法界真如理事之時，顯了分明，此是智慧光明照也。若無智光，則理事不顯。但見法時，是心光明。由積智功圓，是故放一光明，則法界無不顯示。常觀察一切法界，是為放光明照一切也。

First, manifesting radiance: when seeing principle and phenomena of the dharmadhātu and tathatā within the dust mote, they are clearly and distinctly evident, which is the illumination of the radiance of wisdom. If there were no light of wisdom, principle and phenomena would not be manifest. When one merely sees dharmas, it is the radiance of the mind. Because accumulated wisdom has achieved perfection, when one emits a single radiance, there is nothing in the dharmadhātu that is not revealed. Constantly observing all dharmadhātus is emitting radiance to illuminate all.
