起信論疏筆削記 20.27

20.27

引經中，論　修多羅等者，即《阿彌陀》、《無量壽》、《瑞相》及《觀經》等。如《小彌陀經》說：從是西方過十萬億佛土，有世界名曰極樂。樂事極，故名為極樂。有佛號阿彌陀，阿彌陀者，此云無量，光明、壽命、弟子、國土、莊嚴悉無量，故其國土莊嚴，佛身功德微妙殊絕，難可思議，廣在經文，不能具述。

Under 'citing the sūtras,' the treatise states: 'sūtras,' etc., refers to the Amitābha, the Sukhāvatīvyūha, the Ruixiang, the Guan jing, and others. As stated in the Smaller Amitābha-sūtra: 'Passing from here westward beyond a hundred thousand koṭis of Buddha lands, there is a world named Ultimate Bliss (Sukhāvatī).' Because the pleasant things are ultimate, it is named Ultimate Bliss. 'There is a Buddha named Amitābha.' Amitābha is translated here as 'Immeasurable,' because his light, lifespan, disciples, land, and adornments are all immeasurable. Therefore, the adornments of his land and the subtle, wondrous, and supreme merits of the Buddha's body are difficult to conceive; they are extensively treated in the texts of the sūtras and cannot be fully related.
