大方廣佛華嚴經疏 51.12

51.12

大文第二「爾時普賢」下三昧分。普賢入者，是會主故，說普行故。佛華嚴者，萬行披敷，嚴法身故。即以法界行門心海為體，持無限故。說法成行，發起為用，依此能故。

The second major section of text, from "At that time Samantabhadra" onward, is the section on samādhi. Samantabhadra enters it because he is the host of the assembly and expounds universal practice. "Buddha-Avataṃsaka" means the unfolding of the myriad practices to adorn the dharmakāya. It takes the ocean of mind of the practice-doors of the dharmadhātu as its essence, because it upholds what is limitless. Expounding the Dharma to accomplish practice and initiate [realization] serves as its function, because it relies on this capacity.
