金光明經文句記 2.103

2.103

初、明具大智故能理醉。何名大智？謂了性具九界因果，是故名為飲酒法門。真空實相，如《起信論》一真如性，有二種德：一如實空，與過河沙煩惱不相應故；二如實不空，體具河沙功德，無有所少故。護一切失，故空如瓶，德用無礙，故不空如酒。然河沙性德即十法界圓融法門，九界即佛，成前持相；佛界即九，成今犯相。故犯相云「變化五道，宣揚哮吼」，其猶酗酒之用也。

First, clarifying that because one possesses great wisdom, one can be drunk in principle. What is called great wisdom? It means understanding that the nature inherently contains the causes and effects of the nine realms, and therefore it is called the dharma gate of drinking liquor. True emptiness and ultimate reality, as in the single True Suchness nature in the Awakening of Faith, have two kinds of virtues: first, truly empty, because it does not correspond with afflictions numerous as the sands of the Ganges; second, truly not empty, because its essence inherently contains merits numerous as the sands of the Ganges, without lacking anything. Guarding against all faults, it is empty like a flask; its virtuous functions are unobstructed, hence it is not empty like liquor. However, the nature's virtues, numerous as the sands of the Ganges, are the harmonious dharma gates of the ten Dharma realms: the nine realms being the Buddha constitutes the preceding aspect of upholding; the Buddha realm being the nine constitutes the present aspect of breaking. Therefore, regarding the aspect of breaking, it says: "Transforming throughout the five destinies, proclaiming and roaring," which is just like the functioning of intoxication.
