大般涅槃經義記 6.40

6.40

四「我今」下結明說益，謂說空時十恒河沙諸菩薩等得住空地，前略、次廣。

The fourth [section], from "I now..." and below, concludes by clarifying the benefits of the teaching: it means that when emptiness is expounded, bodhisattvas and others as numerous as the sands of ten Ganges Rivers attain abiding in the ground of emptiness; the former was brief, and the next is extensive.
