華嚴經探玄記 4.54

4.54

七進退者，修信未滿一萬劫以還，一切皆退，以是不定聚故。依《本業經》如輕毛隨風等（云云）。設第六有不退心者，但是作此不退之心，以非是位故，未得不退也。亦有人解將此為信不退者。義恐不可，以經中說如輕毛故、無位故；論說修信未經萬劫皆有退故，若至萬劫信便已滿非第六故。若就始教，以隨麁相說信為位，是故今後三賢亦隨相麁說，是故至十迴向以上方得不退，如《佛性論》第一卷說。問：彼論中是敘薩婆多師說，豈是大乘耶？答：雖是薩婆多說，然非彼宗，以說有十迴向名位故。小乘無此位也。若終教中，信滿入住則為不退，如《起信論》信成就發心不退故，及此下文深心淨信不可壞等（云云）。以圓同終故，入位已後方說為不退信也。以因從果稱故，如信忍等。

Seven, progress and regress: when cultivating faith for less than ten thousand kalpas, all regress, because they belong to the indeterminate group. According to the Benye jing, it is like light feathers drifting with the wind, and so forth (and so forth). Even if the sixth has a non-retrogressing mind, it is merely producing this mind of non-retrogression; because it is not a stage, one has not yet attained non-retrogression. Some also interpret this as taking it to be the non-retrogression of faith. The meaning is feared to be unacceptable, because the sūtra speaks of being like light feathers, and of having no stage; and treatises say that those cultivating faith who have not passed ten thousand kalpas all have retrogression; if reaching ten thousand kalpas, faith is already fulfilled, not being the sixth. If in terms of the initial teaching, because it speaks of faith as a stage according to coarse characteristics, the latter three worthies now are also spoken of coarsely according to characteristics; therefore, only upon reaching the ten dedications or above does one attain non-retrogression, as stated in the first fascicle of the Buddha-Nature Treatise. Question: In that treatise, it recounts the explanation of the Sarvāstivāda masters—how could it be Mahāyāna? Answer: Although it is an explanation of the Sarvāstivādins, it is not their doctrine, because it speaks of the names and stages of the ten dedications. The Hīnayāna does not have these stages. In the final teaching, when faith is fulfilled and one enters the abodes, it constitutes non-retrogression, as the Awakening of Faith states that generating the mind upon the completion of faith is non-retrogressing, and as the text below says that profound mind and pure faith cannot be destroyed (and so forth). Because the round is identical to the final, only after entering the stages is it spoken of as faith of non-retrogression. Because the cause is designated in accordance with the fruit, it is like the patience of faith and so forth.
