Sri Aurobindo writing in 6 November 1909, about The Indian Councils Act of 1909 (the Morley-Minto reforms):
''The question of separate representation for the Mahomedan community is one of those momentous issues raised in haste by a statesman unable to appreciate the forces with which he is dealing, which bear fruit no man expected and least of all the ill-advised Frankenstein who was first responsible for its creation. The common belief among Hindus is that the Government have decided to depress the Hindu element in the Indian people by raising the Mahomedan element, and ensure a perpetual preponderance in their own favour by leaning on a Mahomedan vote purchased by a system of preference.
The denials of high-placed officials, who declare that it is only out of a careful consideration for the rights and interests of minorities that they have made special Mahomedan representation an essential feature of the Reform Scheme, have not convinced a single Hindu mind; for the obvious retort is that it is only one minority which is specially cared for and this special care is extended to it even in provinces where it is in a large majority.
No provision at all has been made for the safe-guarding of Hindu minorities, for the Parsis, the Sikhs, the Christians and other sections which may reasonably declare that they too are Indians and citizens of the Empire no less than the Mahomedans...
Our own attitude is clear. We will have no part or lot in reforms which give no popular majority, no substantive control, no opportunity for Indian capacity and statesmanship, no seed of democratic expansion.
We will not for a moment accept separate electorates or separate representation, not because we are opposed to a large Mahomedan influence in popular assemblies when they come but because we will be no party to a distinction which recognises Hindu and Mahomedan as permanently separate political units and thus precludes the growth of a single and indivisible Indian nation.
We oppose any such attempt at division whether it comes from an embarrassed Government seeking for political support or from an embittered Hindu community allowing the passions of the moment to obscure their vision of the future...
The Mahomedans base their separateness and their refusal to regard themselves as Indians first and Mahomedans afterwards on the existence of great Mahomedan nations to which they feel themselves more akin, in spite of our common birth and blood, than to us. Hindus have no such resource. For good or evil, they are bound to the soil and to the soil alone. They cannot deny their Mother, neither can they mutilate her. Our ideal therefore is an Indian Nationalism, largely Hindu in its spirit and traditions, because the Hindu made the land and the people and persists, by the greatness of his past, his civilisation and his culture and his invincible virility, in holding it, but wide enough also to include the Moslem and his culture and traditions and absorb them into itself.''
