大般涅槃經義記 1.50

1.50

「時有無量諸大弟子」，標別其人，學在佛後，故名為弟；從佛化生，故復言子。「迦旃延」等，列其名字。「遇佛光」下，覩相增悲。先別，後結。別中遇光，「其身戰」等，身業不安；「心濁」，意惱；「發聲大喚」，口言傷歎。「如是」下，結。

“At that time there were immeasurable great disciples” identifies the individuals: having studied after the Buddha, they are called “younger brothers” (disciples); being born through transformation from the Buddha, they are also called “sons.” “Kātyāyana” and the others list their names. From “Encountering the Buddha's light” below, beholding the signs, their sorrow increased. It first speaks of them individually, and then concludes. Individually: encountering the light, “their bodies trembled,” and so forth, indicates that their bodily karma was unsettled; “their minds were troubled,” mental distress; “raising their voices in loud cries,” vocal lamentation. From “Thus” below, it concludes.
