無量壽經優婆提舍願生偈註 2.109

2.109

二者彼應化身一切時，不前不後一心一念放大光明，悉能遍至十方世界教化眾生種種方便修行所作，滅除一切眾生苦故。偈言「無垢莊嚴光，一念及一時，普照諸佛會，利益諸群生」故。

"Second, in all times, neither earlier nor later, with one mind and in a single thought-moment, those adaptive transformation bodies emit great light, which can reach everywhere across the worlds of the ten directions to educate and transform sentient beings through various skillful means, practices, and deeds, in order to extinguish all sentient beings' suffering." Because the verse states: / "The immaculate, adorned light, / In a single thought-moment and at the same time, / Universally illuminates the assemblies of the Buddhas, / Benefiting all sentient beings."
