觀無量壽佛經疏 4.26

4.26

Furthermore, all practitioners, walking, standing, sitting, or lying down, in cultivating the three karmas, regardless of day, night, or season, should constantly form this understanding and constantly maintain this thought; therefore it is called the mind of pariṇāmanā and making vows. Moreover, 'pariṇāmanā' also means that after being born in that land, one turns back to give rise to great compassion, returning to enter birth-and-death to teach and transform sentient beings; this is also called pariṇāmanā. When the three minds are complete, no practice fails to be accomplished. When vows and practice are already accomplished, that one should fail to be reborn is impossible. Furthermore, it should be known that these three minds also comprehensively encompass the meaning of the meditative good.
