大乘起信論廣釋卷第三．四．五 5.115

5.115

論。復次至意欲退者　釋曰。修行信心下有三所由。前來已顯就人□意約法廣辨。次下第三隨退方便。於中有二。初舉可退之人。後防退之法。此初也。初學是法者。此明行劣。以住已下舉處釋成。內心既劣。外闕勝緣。信行難成。故將退也。即是將退入二乘道。新論更加能具惡緣。故彼文云。或值寒熱風雨不時飢饉等苦。或見不善可畏眾生。三毒所纏邪見顛倒。棄背善道習行惡法。菩薩在中心生怯弱。恐不值遇諸佛菩薩。恐不能成清淨信心。生疑欲退。文雖廣略大意同也。

[Treatise:] Furthermore, [there are sentient beings whose faith has not yet been established since they first began to study this Dharma, and when they dwell in this sahā world, their minds wish to retrogress.]
[Commentary:] Under "cultivating faith" there were three reasons. Previously it was shown that with regard to persons [...] the intention was broadly distinguished according to phenomena. Next is the third: skillful means in accord with retrogression. In this there are two: first, citing the person who may retrogress; and next, the method to prevent retrogression. This is the first. "Those who first began to study this Dharma" clarifies their inferior practice. From "dwelling in" onward, it cites the place to explain and complete [the point]. Since their inner mind is inferior and externally they lack superior conditions, their practice of faith is difficult to complete, and thus they are about to retrogress. That is, they are about to retrogress into the path of the two vehicles. The new translation adds that they fully encounter bad conditions, for that text says: "Or they encounter cold, heat, untimely wind and rain, famine, and other sufferings; or they see evil and frightening sentient beings, entangled in the three poisons, with wrong views and inversions, who abandon the good path and practice evil dharmas. The bodhisattva dwelling in their midst generates timidity and cowardice, fearing that they will not encounter the buddhas and bodhisattvas, and fearing that they will not be able to achieve pure faith, so they generate doubt and wish to retrogress." Although the texts are broad or concise, their general intent is identical.
