新譯華嚴經七處九會頌釋章 1.20

1.20

釋曰：舍那法會充遍塵剎，難測涯限，且寄分相迹，釋說經會，略有四門：一定其說處門、二融攝無礙門、三顯處差別門、四表示法勝門。

The commentary states: Rocana's Dharma assemblies pervade the dust-mote realms and their boundaries are difficult to measure. Setting aside [the ultimate and] provisionally relying on the traces of differentiated characteristics to explain the assemblies in which the sūtra was preached, there are briefly four gates: first, the gate of determining the places of preaching; second, the gate of unimpeded harmonious integration; third, the gate of displaying the differences among the places; fourth, the gate of symbolizing the supremacy of the Dharma.
