仁王護國般若波羅蜜多經疏 3.350

3.350

解曰：於無相忍者，智緣無相，名無相忍也。而得三明者，一宿住智明、二死生智明、三漏盡智明，廣如前解。悉知三世無來無去者，由此三明，初知過去、次知未來、後知現在，了知三世達彼體空，無來去矣。從此第二明所修定。

The commentary states: "In signless kṣānti" means that wisdom takes the signless as its object, hence it is named "signless kṣānti." "Attains the three knowledges": first, the clear knowledge of recollection of past abodes; second, the clear knowledge of death and birth; third, the clear knowledge of the exhaustion of outflows, as explained extensively before. "Completely knowing that the three times have neither coming nor going": through these three knowledges, one first knows the past, next knows the future, and later knows the present, thoroughly knowing the three times and understanding that their substance is empty, with neither coming nor going. From here, the second [part] explains the concentrations cultivated.
