大乘起信論義記 1.85

1.85

The second serves as the condition for the below [passage on] "Differentiating the Characteristics of Setting Forth toward the Path." This is because that text causes those of sharp faculties to generate a resolute mind, advance toward the Great Path, and be capable of the stage of non-retrogression (the abodes). This corresponds to the final mind of the ten faiths, where one's own portion is fulfilled; hence it says "wholesome roots have matured." Entering into the correct determination of the ten abodes enables the preceding faithful mind to become capable of non-retrogression.
