妙法蓮華經玄贊 7.291

7.291

贊曰：果記。有六，此自體也。迦延過去曾掃僧地，身常金色容儀閑雅，今復目覩毫光、耳聽法光，故名閻浮金光。廣如《樞要》度鉢代多王事。瞻部那提是樹名，在此洲無，熱池岸側。有經在此洲北岸，近樹下有紫金光映弊日月。

The Commentary says: This is the prophecy of fruition. There are six aspects; this is his own-nature. In the past, Kātyāyana once swept the monastic grounds, so his body was constantly golden in color and his deportment graceful and tranquil. Now he again beholds the ūrṇā light with his eyes and hears the light of the Dharma with his ears; hence his name is Jambūnada-prabhāsa (Golden Light of the Jambu River). It is explained in detail in the Shunyao, in the story of King Duobadaiduo. 'Jambū-nadī' is the name of a tree; it does not exist on this continent, [growing only] beside the Anavatapta lake. One sūtra says that on the northern shore of this continent, close beneath the tree, there is a purple-golden radiance that outshines the sun and moon.
