阿彌陀經疏 1.22

1.22

Third, the virtue of the great assembly: because the sentient beings who are born there are all non-retrogressive (avaivartika), and those who are born in that land through even the virtue of ten recitations enter the stage of certainty and never regress. The treatise asks: What is the fulfillment of the virtue of adorning the great assembly? The verse states: / 'The immovable assembly of humans and devas / Is born from the ocean of pure wisdom.' / The commentary states: All rely on being nurtured by the Tathāgata's ocean of wisdom, entering the stage of certainty without wavering or turning back.
