無量壽經優婆提舍願生偈註 2.39

2.39

此云何不思議？譬如迦羅求羅蟲其形微小，若得大風身如大山，隨風大小為己身相。生安樂眾生亦復如是，生彼正道世界即成就出世善根入正定聚，亦如彼風非身而身，焉可思議？

How is this inconceivable? For example, the kālakūla insect has a tiny form, but when it encounters a great wind, its body becomes like a great mountain, taking the size of the wind as its own bodily form. Sentient beings reborn in [the Land of] Peace and Bliss are also like this: being reborn in that world of the correct path, they immediately accomplish worldly-transcending roots of goodness and enter the group of correct determination, just as that wind is not a body yet becomes a body—how could it be conceivable?
