And this is the meaning of:xiMishnah Avot 5:17 ‘a dispute which is for the sake of heaven, whose purpose will endure’, to bring about peace and unity in both-of-them, and not a dispute of separation, such as the dispute of Koraḥ and his assembly with Aaron.
And this debate which is for the sake of Heaven is because the lower waters are crying, and saying: ‘We want to be before the King, the Cause of all causes!’ And they want to ascend above. But a firmament separates between them, until the Cause of all causes makes them equal.
