觀念阿彌陀佛相海三昧功德法門 1.66

1.66

又如下經云，佛告阿難：「如此妙華是本法藏比丘願力所成。若欲念彼佛者，當先作此華座想，一一觀之皆令分明，此想成者必定當生極樂世界。」又以此經證，亦是證生增上緣。

Furthermore, the sūtra below says that the Buddha addressed Ānanda: "Such wonderful flowers were accomplished by the power of the monk Dharmākara's original vows. If you wish to contemplate that Buddha, you should first visualize this flower throne, contemplating each part clearly; when this visualization is accomplished, one will certainly be born in Sukhāvatī." Again taking this sūtra as proof, this too is the adhipati-pratyaya of certifying rebirth.
