Patience of non-arising (anutpattika-dharma-kṣānti) means being patient with the fact that the five-aggregate body is produced 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 give rise to all 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 stage of the three wholesome roots (the three stages before bhūmi attainment), and one has not yet entered the noble stages.
The patience regarding the non-arising of dharmas (anutpattika-dharma-kṣānti) is built upon the patience of non-arising: one realizes that all dharmas are also non-arising, realizes the consciousness-only nature of all dharmas, and subdues self-grasping (though not yet eliminated); only then does one enter the noble stages and abide there without regression.
