瑜伽師地論略纂 9.81

9.81

論解第二果與初果稍有差別中云「謂若行境界等，乃至速疾除遣」，與初果人第二相別也；又「唯一度來生此世間」者，此與初果人第十一法別也。合初二果，有二相差別。

Where the treatise explains that the second fruit has a slight difference from the first fruit, stating, "namely, if while coursing in an intentional domain, and so forth, up to: swiftly dispelling it": this differs from the second characteristic of a person of the first fruit; furthermore, "coming to be born in this world only once": this differs from the eleventh dharma of a person of the first fruit. Combining the first and second fruits, there are two characteristics of difference.
