大乘起信論義記 3.515

3.515

當知如來有勝方便攝護信心，謂以專意念佛因緣，隨願得生他方佛土，常見於佛永離惡道。

One should know that the Tathāgata has superior skillful means to protect and maintain faith: namely, that by the cause and condition of single-mindedly being mindful of the Buddha, according to one's vow one can be reborn in another Buddha's land, constantly see the Buddha, and be forever freed from the miserable paths.
