註華嚴法界觀門 1.8

1.8

所依經也。大方廣是所證法，佛華嚴是能證人。大者體也，諸佛眾生之心體。方廣，即體之相用。佛者果也。華嚴因也。華喻萬行，嚴即大智。大智為主，運於萬行，嚴大方廣，成佛果也。略無經字，意不在文。

The sūtra relied upon. "Mahāvaipulya" (great, correct, and broad) is the realised dharma; "Buddha-avataṃsaka" (Buddha adorned with flowers) is the person who can realise it. "Great" is the substance: the mind-substance of all buddhas and sentient beings. "Correct and broad" refers to the characteristics and functioning of the substance. "Buddha" is the fruition. "Flower-adornment" is the cause. "Flowers" metaphorically represent the myriad practices; "adornment" is great wisdom. Great wisdom as the host deploys the myriad practices to adorn the Mahāvaipulya and achieve the fruition of buddhahood. Omitting the word "sūtra" indicates that the intention is not on the text.
