阿彌陀經通贊疏 2.126

2.126

Answer: 'Because they lack the five conditions for retrogression: first, they are not entangled in the suffering of illness; second, they lack contrary practices; third, they constantly recite the sūtras and teachings; fourth, they constantly engage in wholesome deeds; fifth, they are ever harmonious and gentle, without contentious disputes—therefore they do not retrogress. People in this world mostly retrogress; you should understand the contrary of this. Furthermore, pulled by objects of desire, there is much retrogression and faltering.'
