大乘起信論義記 3.312

3.312

若有眾生善根微少，久遠已來煩惱深厚，雖值於佛亦得供養，然起人天種子，或起二乘種子。設有求大乘者，根則不定，若進若退。

If there are sentient beings whose wholesome roots are slight and few, whose afflictions have been deep and heavy since long ago, even though they meet buddhas and are able to make offerings to them, they nevertheless give rise to the seeds of humans and gods, or give rise to the seeds of the two vehicles. Even if there are those who seek the Mahāyāna, their faculties are unfixed, either advancing or retrogressing.
