Question on becoming from HSG

[Firgrep]

Great question asked on the HSG on facebook

So Hegel says “Becoming is an unstable unrest which settles into a stable result” and “it is the unity of being and nothing which has settled into a stable oneness.”
My question is how do we get from Becoming to this oneness? Why doesn’t Becoming simply keep alternating between coming-to-be and ceasing-to-be forever?
Is it that, because Being and Nothing have vanished into each other, they are no longer distinguished, hence the “vanishing of the vanishing?”
Or maybe this stable oneness is the equilibrium between coming-to-be and ceasing-to-be, as in they “cancel” each other out and leave the whole with no net “motion?” If this is the case, would it be right to say that the coming-to-be and ceasing-to-be never actually stop, it just seems like they’ve stopped (from the POV of determinate being) because they’re in equilibrium?

Does our own account on becoming answer this? What can be improved?
