大般涅槃經集解 2.37

2.37

Sengliang states: Previously he announced it to let them know; now he removes their karmic obstacles.
Sengzong states: "Sin" refers to the fruit; "defilement and affliction" refer to the cause.
Baoliang states: Speaking here of "extinguishing" is based on suppression and removal. It means that when those who behold the light direct their minds to the supreme realm, the three poisons cannot arise concurrently; they only produce pure minds, hence it says "sins were extinguished".
