There are some who say, “The statement that by recitation of the Holy Name of Amideva one may be born in the Pure Land is an example of a temporally displaced intention. Rebirth may refer to a birth many lifetimes removed. Even if you were to practice in accord with what is stated in this Sutra of the Pure Land, you will not be born in that Land in the next life.” This harms sentient beings by becoming the basis for the rejection of the doctrine, and for doubt.
This doubt is dispelled by Bodhisattva Dharmakara’s nineteenth vow. One must (1) part far from the five deeds bringing immediate retribution (matricide, patricide, killing an arhat, wounding the body of a Buddha, and promoting schisms in the Sangha), (2) avoid slander and rejection of the Dharma, and (3) engender the definitive aspiration for the enlightenment of all sentient beings.
Rebirth in the Pure Land is achieved by the essential practice of recitation of the Holy Name, accompanied by these three auxiliary practices.
