大方廣佛華嚴經隨疏演義鈔 26.24

26.24

疏「第五段剎莊嚴中至或寶為嚴」等者，然莊嚴有三，即名三淨：一處所淨，即眾寶為嚴；二住處眾生淨，即人寶為嚴；三法門流布淨，即以法為嚴。對文可知。

Regarding the commentary's "In the fifth section, on the adornment of the kṣetra, down to 'or jewels serve as adornments'" and so forth: adornment has three aspects, which are called the three purities: 1. Purity of location, which is adornment with various jewels; 2. Purity of the sentient beings dwelling therein, which is adornment with human jewels; 3. Purity of the dissemination of the Dharma gates, which is adornment with the Dharma. This can be understood by comparing it with the text.
