Humanity has long sought an answer to achieving a harmonious social order. Generally this involves either conquering or assimilating diverse peoples so as to create, in the end, a homogeneous society with a fixed set of organized standards for everyone to follow. The mental approach is to believe that if we all look the same, wear the same clothes, eat the same food, and think the same thoughts, we will have harmony. In the end, these attempts have failed, both because they are not aligned with the diversity of Nature, and because they breed stagnation through an emphasis on uniformity.
From a supramental perspective, however, the limitations of the mind’s process disappear. Just as we see virtually infinite diversity of forms in the natural order, each fitting into a complex biosphere and ecosphere, each having its role and its own forms of growth and fulfillment, so in human society we could see and encourage the diversity of people and find their oneness, not in uniformity of thought or action, but in mutual good will and understanding and support for their various forms of life and expression.
Sri Aurobindo writes in The Life Divine: “A similar inevitability of the union of freedom and order would be the law of the collective life; it would be a freedom of the diverse play of the Infinite in divine souls, an order of the conscious unity of souls which is the law of the supramental Infinite. Our mental rendering of oneness brings into it the rule of sameness; a complete oneness brought about by the mental reason drives towards a thoroughgoing standardisation as its one effective means, — only minor shades of differentiation would be allowed to operate: but the greatest richness of diversity in the self-expression of oneness would be the law of the gnostic life. In the gnostic consciousness difference would not lead to discord but to a spontaneous natural adaptation, a sense of complementary plenitude, a rich many-sided execution of the thing to be collectively known, done, worked out in life.”
