觀無量壽佛經義疏 3.67

3.67

「『作此觀者，捨身他世生諸佛前，得無生忍。』」捨身他世生彼土已即證無生，故知此觀若成則上品上生明矣。三、勸修，二：初、勸觀；二、教入處。初、勸觀。

"[The Buddha said:] 'Those who perform this contemplation, upon discarding this body in another life, will be born before all the Buddhas and attain anutpattika-dharma-kṣānti.'" Discarding the body in another life and being born in that land, one immediately realizes non-arising; thus we know that if this contemplation is accomplished, one will clearly attain the highest level of the superior grade of rebirth. Third, exhortation to practice, which has two parts: first, exhorting the contemplation; second, teaching the entry point. First, exhorting the contemplation.
