大乘起信論裂網疏 6.133

6.133

如經中說：若善男子善女人專念西方極樂世界阿彌陀佛，以諸善根迴向願生，決定得生，常見彼佛，信心增長，永不退轉。於彼聞法觀佛法身，漸次修行，得入正位。

As the sūtras explain: 'If a good man or good woman exclusively mindfully recollects the Buddha Amitābha of the Western Land of Ultimate Bliss, dedicatedly directing all roots of goodness with the wish to be reborn there, they will definitely attain rebirth, constantly see that Buddha, have their faith increase, and never regress. Hearing the Dharma there and contemplating the Buddha's Dharmakāya, they will gradually cultivate practice and attain entry into the correct stage.'
