Patience with non-arising (anutpattika-dharma-kṣānti at the preliminary level) means being patient with the fact that the five-aggregate body is generated and sustained by the tathāgatagarbha, being patient with the fact that the five-aggregate body is empty, illusory, and without self, and being patient with the fact that the tathāgatagarbha neither arises nor ceases, can generate the myriad dharmas, dwells within the five-aggregate body, and life after life transforms and generates one's own five aggregates. According to the degree of one's realization, this is limited to the three stages of the wise (three virtuous stages), not yet having entered the noble stages.
Patience with the non-arising of dharmas (anutpattika-dharma-kṣānti) is built upon the foundation of patience with non-arising, realizing that all dharmas are also non-arising, realizing the consciousness-only nature of all dharmas, and subduing the grasping of self (though not yet eradicated); only then does one enter the noble stages and abide without regression.
