無量壽經優婆提舍願生偈註 2.74

2.74

此云何不思議？彼國人天若欲願往他方世界無量佛剎供養諸佛菩薩，及所須供養之具，無不稱願。又欲捨彼壽命向餘國生，修短自在，隨願皆得。未階自在之位而同自在之用，焉可思議？

How is this inconceivable? If the humans and devas of that land wish to go to immeasurable Buddha-lands in other directions to make offerings to the Buddhas and bodhisattvas, and to obtain the necessary articles of offering, everything accords with their wishes. Furthermore, if they wish to relinquish their lifespan there and be born in other lands, whether long or short is at their mastery, and all is obtained according to their wish. That before reaching the stage of mastery, they share in the functioning of mastery—how could this be conceivable?
