It is hardly possible to say what the supermind is in the language of Mind, even spiritualised Mind, for it is a different consciousness altogether and acts in a different way. Whatever may be said of it is likely to be not understood or misunderstood. It is only by growing into it that we can know what it is and this also cannot be done until after a long process by which mind heightening and illuminating becomes pure Intuition (not the mixed thing that ordinarily goes by that name) and masses itself into overmind; after that overmind can be lifted into and suffused with supermind till it undergoes a transformation.
In the supermind all is self-known self-luminously, there are no divisions, oppositions or separated aspects as in Mind whose principle is division of Knowledge into parts and setting each part against another. Overmind approaches this at its top and is often mistaken for supermind, but it cannot reach it – except by uplifting and transformation.
