大般涅槃經集解 2.47

2.47

Sengliang states: The three auspicious signs above were the causes and conditions for assembling the multitude; below this describes the sequence of the assembly. The "great disciples" were already at the Buddha's side; hence it does not speak of their coming.
Daohui's Notes state: These are precisely the eighty hundred thousand koṭis mentioned before. Since they were not summoned by the voice and light, the reason they are listed again is to describe their grief and distress upon encountering the light.
Huilang states: This brings up the afflictions of the three karmas, namely the body trembling and the disturbed mind uttering sounds.
