10.393

言由無染心者，無志善根也。純悲愍故者，眾生緣悲也，看此後文順於前解。泰述四釋。一云，思慧忍名思擇力，修慧忍名自性，以修慧自性能堪忍故。二云：地前忍者思擇力，由作意故，地上忍名自性忍，任運起故。三云：初學忍名思擇力，久學成名自性忍，前忍遍一切皆能忍，後忍普一切皆能忍，又釋，遍一切眾生皆能忍，普於一切事皆能忍，一眾生中有多事，謂或打或罵等事非一故也。

The phrase 'due to an undefiled mind' refers to the roots of virtue of lack of craving. 'Due to pure compassion' refers to compassion oriented toward sentient beings; looking at the later text, it accords with the previous explanation. Tai presents four explanations. The first says: patience of reflective wisdom is called the power of reflective consideration, while patience of cultivated wisdom is called the essential nature, because the essential nature of cultivated wisdom is capable of enduring. The second says: patience prior to the stages is the power of reflective consideration, because it arises through intentional mental engagement, whereas patience on the stages is called essential nature patience, because it arises spontaneously. The third says: the patience of a beginner is called the power of reflective consideration, while that achieved through long practice is called essential nature patience. The former patience is able to endure pervasively toward all, while the latter patience is able to endure universally toward all. Another explanation is: being able to endure pervasively toward all sentient beings, and being able to endure universally toward all situations; within a single sentient being there are many situations, meaning multiple situations such as being struck or being scolded.
