三、諸心皆染失。謂答離無漏慧明是無明者，凡夫身中三性心皆至離慧明，是則三性心法皆應成染，以彼無明是染法故。

Third, the fault of all minds being defiled. That is, if one answers that being apart from the bright knowledge of taintless wisdom is ignorance, then in an ordinary being's body, minds of all three natures are apart from bright wisdom; if so, mind and mental dharmas of all three natures should all become defiled, because that ignorance is a defiled dharma.
