無量壽經優婆提舍願生偈註 2.126

2.126

問曰：言眾生清淨，則是佛與菩薩；彼諸人天得入此清淨數不？答曰：得名清淨，非實清淨。譬如出家聖人，以殺煩惱賊故名為比丘。凡夫出家者，持戒破戒皆名比丘。又如灌頂王子，初生之時具三十二相，即為七寶所屬。雖未能為轉輪王事，亦名轉輪王，以其必為轉輪王故。彼諸人天亦復如是，皆入大乘正定之聚，畢竟當得清淨法身，以當得故得名清淨。

Question: When 'the purity of sentient beings' is mentioned, that refers to Buddhas and bodhisattvas. Are those humans and devas [in that land] counted in this purity or not? Answer: They obtain the name 'pure,' but are not truly pure. For example, a holy person who has left home is called a bhikṣu because he has slain the thieves of defilement. Ordinary people who have left home, whether keeping the precepts or breaking the precepts, are all called bhikṣus. Again, it is like an anointed prince who, when newly born, possesses the thirty-two marks and is already the owner of the seven treasures. Although he is not yet able to carry out the affairs of a wheel-turning king, he is still called a wheel-turning king, because he will certainly become a wheel-turning king. Those humans and devas are also like this: they all enter the Mahāyāna group of correct determination and will ultimately attain the pure Dharma body. Because they will attain it, they obtain the name 'pure.'
