大乘起信論略述 2.123

2.123

論。所謂依不定聚眾生　述曰。下答有二。初正答前問。後舉劣顯勝。前中亦二。先別答。三問。後結成入位。前答三問。即分為三。此顯修人。答初問也。分別三聚乃有四門。今者唯就約位分別。十住已上名正定聚。住聖種故。未入十信名邪定聚。背正因故。中間十信名不定聚。行進退故。今依此人明所修行。故言依不定聚眾生也。

[Treatise:] "That is, relying on sentient beings of indeterminate destiny..." [Commentary:] The answer below has two parts: first, directly answering the previous question; second, presenting the inferior to reveal the superior. In the first part there are also two: first, answering the three questions separately; second, concluding with entering the stages. Answering the three questions is divided into three. This reveals the practitioner, answering the first question. Differentiating the three destinies involves four approaches; here, it is differentiated purely in terms of stages. From the ten abodes upward is called the destiny of absolute certainty, because one abides in the noble lineage. Those who have not yet entered the ten faiths are called the destiny of absolute falsehood, because they turn their backs on the correct cause. The intermediate ten faiths are called the indeterminate destiny, because their practice advances and regresses. Now, in reliance on this person, the practice performed is clarified; hence it says, "relying on sentient beings of indeterminate destiny."
