淨土生無生論 1.19

1.19

《佛說阿彌陀經》云：「從是西方過十萬億佛土，有世界名曰極樂。」百億日月，百億須彌，百億大海，百億鐵圍山，名一佛土。十千為萬，十萬為億。一佛國土已自廣大，況億佛國土乎？況十萬億乎？是則極樂去此甚遠。博地凡夫念佛求生，彈指即到者，正由生吾心所具之佛土也。言介爾心者，即凡夫念佛之心也。剎那之心至微至劣，故稱介爾。謂十萬億遠之佛土，居於凡夫介爾之心，即心是土，即土是心，故曰「初無彼此異」。

The Sūtra Spoken by the Buddha on Amitābha says: 'Passing from here westward through a hundred thousand koṭis of Buddha-lands, there is a world named Ultimate Bliss.' One billion suns and moons, one billion Mount Merus, one billion great oceans, and one billion Iron Ring Mountains are called one Buddha-land. Ten thousand is wan; one hundred thousand is yi. A single Buddha-land is already vast; how much more so a koṭi of Buddha-lands? How much more so a hundred thousand koṭis? Thus Ultimate Bliss is extremely distant from here. Yet when ordinary beings bound to the earth recite the Buddha's name seeking birth, they arrive there in the snap of a finger, precisely because they are born into the Buddha-land contained in our own mind. The so-called 'single momentary thought-mind' is precisely the ordinary being's mind that recites the Buddha's name. A mind of a single kṣaṇa is extremely minute and inferior, hence it is termed 'a single momentary thought.' This means that the Buddha-land as distant as a hundred thousand koṭis resides within the ordinary being's single momentary thought-mind: the mind itself is the land, the land itself is the mind; therefore it is said, 'From the beginning there has been no difference between this and that.'
