大方廣佛華嚴經隨疏演義鈔 85.6

85.6

Regarding the Commentary's "Fourth, determining the names and meanings of the assemblies," it means that although no Buddha was speaking, it is called a sūtra assembly because the root unifies the branches. As for "lanshang" (source/beginning), lan means overflowing, and shang means a wine cup. It means that when the Yangtze River emerges from Mount Min, its initial source can only float a wine cup. Although what emerges is small, its source lies here; thus, though it runs for thousands or tens of thousands of li, it is said that "the Yangtze River emerges from Mount Min." Therefore, even though they are scattered across various directions, they are called sūtra assemblies. The Commentary's text from "If so" onward resolves doubts and is self-evident.
