According to the Vedic tradition, Existence can be divided into two hemispheres, the lower half and the upper half. The upper half is the original while the lower is its divided reflection. The higher hemisphere is based on Oneness because all the beings, forces, energies there are conscious of the One Origin. The lower half is based on division because all its beings, forces, energies experience and act as if they are separate and independent from the One Origin. This division is the origin of Ignorance and its attendant disharmony, disorder, falsehood, evil and suffering. Overmind is the highest peak of this lower hemisphere. Here Ignorance is like a translucent shade and the background sense of Oneness is still there. This is the plane of the great Gods.
Supermind is that point in the higher hemisphere where it begins to differentiate the One into Its manifold aspects and possibilities. Thus it becomes the link between the higher and lower hemispheres.
Below is an excerpt from the Mother on the subject.

Words of the Mother:
“Supermind and Overmind.
Sri Aurobindo’s work is a unique earth-transformation.
Above the mind there are several levels of conscious being, among which the really divine world is what Sri Aurobindo has called the Supermind, the world of the Truth. But in between is what he has distinguished as the Overmind, the world of the cosmic Gods. Now it is this Overmind that has up to the present governed our world: it is the highest that man has been able to attain in illumined consciousness. It has been taken for the Supreme Divine and all those who have reached it have never for a moment doubted that they have touched the true Spirit. For, its splendours are so great to the ordinary human consciousness that it is absolutely dazzled into believing that here at last is the crowning reality. And yet the fact is that the Overmind is far below the true Divine. It is not the authentic home of the Truth. It is only the domain of the formateurs, all those creative powers and deities to whom men have bowed down since the beginning of history. And the reason why the true Divine has not manifested and transformed the earth-nature is precisely that the Overmind has been mistaken for the Supermind. The cosmic Gods do not wholly live in the Truth-Consciousness: they are only in touch with it and represent, each of them, an aspect of its glories.
No doubt, the Supermind has also acted in the history of the world but always through the Overmind. It is the direct descent of the Supramental Consciousness and Power that alone can utterly re-create life in terms of the Spirit. For, in the Overmind there is already the play of possibilities which marks the beginning of this lower triple world of Mind, Life and Matter in which we have our existence. And whenever there is this play and not the spontaneous and infallible working of the innate Truth of the Spirit, there is the seed of distortion and ignorance. Not that the Overmind is a field of ignorance; but it is the border-line between the Higher and the Lower, for, the play of possibilities, of separate even if not yet divided choice, is likely to lead to deviation from the Truth of things.
The Overmind, therefore, does not and cannot possess the power to transform humanity into divine nature. For that, the Supramental is the sole effective agent. And what exactly differentiates our Yoga from attempts in the past to spiritualise life is that we know that the splendours of the Overmind are not the highest reality but only an intermediate step between the mind and the true Divine.’
