“Sariputra, if there are people who have already made the vow, who now make the vow, or who are about to make the vow, ‘I desire to be born in Amitabha’s country,’ these people, whether born in the past, now being born, or to be born in the future, all will irreversibly attain to anuttarasamyaksambodhi. Therefore, Sariputra, all good men and good women, if they are among those who have faith, should make the vow, ‘I will be born in that country.’”
~ Amitabha Sutra
When I obtain the Buddhahood, any being of the boundless and inconceivable Buddha-worlds of the ten quarters whose body if be touched by the rays of my splendour should not make his body and mind gentle and peaceful, in such a state that he is far more sublime than the gods and men, then may I not attain the enlightenment.
~ Amitabha Buddha's Thirty-Third Vow
