大乘起信論別記 1.190

1.190

發趣分中，信成就發心，位在十解前，在不定聚時修習信心逕一萬劫，信心成就，入正定位，即是十解，亦名十住，亦名十信，亦名習種性。如《本業經》云「是信相善菩薩，於十千劫，行十戒法，當入十信心，入初住位。」《仁王經》云「習種性有十心，已超二乘一切善地。此習忍已前，行十善菩薩，有退有進，猶如輕毛隨風東西，雖以十千劫行十正道，發菩提心，乃當入習種性。」彼經云十千，此論一萬同一數也。

In the section on proceeding toward [enlightenment], the cittotpāda of accomplished faith is situated prior to the ten understandings. While in the indeterminate group, one cultivates faith for ten thousand kalpas; when faith is accomplished, one enters the correctly determined group, which is precisely the ten understandings, also called the ten abodes, also called the ten faiths, and also called the nature of practice lineage. As the Benye jing states: "This bodhisattva of good faith characteristics, for ten thousand kalpas, practices the ten precepts and shall enter the ten minds of faith, entering the stage of the first abode." The Renwang jing states: "The nature of practice lineage has ten minds, which have already surpassed all good stages of the two vehicles. Prior to this patience of practice, the bodhisattva practicing the ten goods has retreat and advance, just like a light feather moving east and west with the wind; although practicing the ten correct paths for ten thousand kalpas and generating the bodhicitta, only then will they enter the nature of practice lineage." That sūtra says "ten thousand" [using ten thousands], and this treatise says "one myriad"; they are the same number.
