無量壽經優婆提舍願生偈註 2.148

2.148

菩提是安穩一切眾生清淨處，若不作心拔一切眾生離生死苦，即便違菩提，是故拔一切眾生苦是順菩提門。

Bodhi is the pure place of peace and stability for all sentient beings. If one does not set one's mind to pulling all sentient beings out of the suffering of birth and death, one immediately goes against bodhi. Therefore, pulling out the suffering of all sentient beings is a gate of compliance with bodhi.
