三彌勒經疏 1.136

1.136

經曰「佛告優波離汝今」以下，第二勸歸聖得利。多陀阿加度者翻如來，阿羅呵者反應供，三藐三佛陀者反正遍知也。

From the sūtra's words 'The Buddha addressed Upāli, you now' onward, this is the second part, exhorting them to take refuge in the holy one and attain benefit. 'Tathāgata' translates as 'thus-come'; 'arhat' corresponds to 'worthy of offerings'; 'samyaksaṃbuddha' corresponds to 'correctly and fully enlightened one'.
