Whether or not there is the arising of Tathagatas, this property stands — this steadfastness of the Dharma, this orderliness of the Dharma: All phenomena are devoid of self.
The Tathagata directly awakens to that, breaks through to that. Directly awakening and breaking through to that, he declares it, teaches it, describes it, sets it forth. He reveals it, explains it, and makes it plain: All phenomena are devoid of self.
—Buddha Shakyamuni, Dharma-niyāma Sutra
