大般涅槃經義記 1.89

1.89

自下第七重明諸眾覩相增悲，獻奉供養。於中有二：一明此方所集諸眾覩相增悲，獻奉供養；二「爾時東方去此」已下明他方眾雲集獻供。就初段中先明覩相，皆悉悲感，是增悲也，名前變林為涅槃相，下明獻供。

From here below is the seventh section: clarifying again that all the assemblies, beholding the marks, grew in sorrow and presented offerings. Within this there are two parts: first, clarifying that the assemblies gathered in this world, beholding the marks, grew in sorrow and presented offerings; second, from "At that time, from the east, departing from this [world]..." downward, clarifying that the assemblies of other worlds gathered like clouds to present offerings. In the first section, it first clarifies that beholding the marks they all felt grief and sorrow—this is the increase of sorrow. The preceding transformation of the grove is called the mark of nirvāṇa; below, it clarifies their presenting offerings.
