無量壽經優婆提舍願生偈註 2.14

2.14

Why is this said? The practice of bodhisattvas is constantly to worship all the Buddhas of the ten directions during the three periods of the day and the three periods of the night, without necessarily having the intention to aspire for rebirth; now one should constantly generate the intention to aspire for rebirth, and therefore one worships Amitābha Tathāgata.
