觀無量壽佛經義疏 3.132

3.132

"The Buddha told Ānanda and Vaidehī, ‘Those of the highest level of the highest rank:’" Second, explaining it has four [parts]: first, the cultivation of the causes; second, eliciting the superior conditions; third, obtaining rebirth upon seeing [them]; and fourth, the benefits after rebirth. First, the cultivation of the causes has two [parts]: first, arousing the three minds; and second, cultivating the three practices. First, arousing the three minds.
