大般涅槃經集解 2.39

2.39

Sengliang states: Defilements and obstacles having been eliminated, feelings of longing and yearning arose. Grief and confusion disordered their minds, giving them no way to assemble quickly; therefore, by spiritual power he shook the earth to restrain their sorrowful feelings.
Fayao states: Even insentient things still move, how much more so those with minds! By moving the people of the time, he caused them to gather quickly like clouds.
Sengzong states: This is the third mark. The Tathāgata's supreme virtue is like the earth in pacifying the multitude of living beings. Relinquishing transformation and returning to the real, he displays it to make them awaken.
Zhixiu states: Having seen the earth shake, three thoughts arose: first, urging one another to restrain themselves for the moment; second, that they must now go quickly, go quickly; third, that if they later have doubts, there will be no one to consult.
Huilang states: Below this are two stages; this is the first, narrating the mark of the earth shaking.
