華嚴經探玄記 5.18

5.18

第二放光序中六：一放光人。二光出處，謂如足指按地乃得住立，表此十住成位不退，故名住也。三光數。四光相，謂解相炳著故云妙色，亦是名也。五光照處，謂是上〈光覺品〉所辨，又是諸文結通之處。前品佛力顯現菩提樹下諸身，今光照樹下及天上。六如來大眾等，明照所顯現通同為一法界圓明之會故也。又云樹下須彌頂知之。

Second, in the preface to emitting light, there are six [points]: first, the person emitting the light; second, the place from which the light emerges, meaning that just as one can stand firmly only when one's toes press the ground, this symbolizes that in these ten abidings the stage is achieved and there is no regression, hence called "abiding"; third, the number of lights; fourth, the marks of the light, meaning that because the marks of understanding are brilliantly manifest it is called "wondrous color," which is also its name; fifth, the places illuminated by the light, which are what was analyzed above in the "Chapter on Illumination and Awakening," and are also where the various passages conclude with universal pervading. In the preceding chapter, the Buddha's spiritual power made manifest the various bodies beneath the bodhi tree; now the light illuminates beneath the tree and up in the heavens; sixth, the Tathāgata and the great assembly, and so forth, clarifying that what is illuminated and manifest pervades together as one assembly of the dharmadhātu's perfect radiance. Further, it is known from the phrase "beneath the tree and at the peak of Mount Sumeru."
