The quintessential revolution is that of the spirit, born of an intellectual conviction of the need for change in those mental attitudes and values which shape the course of a nation's development. A revolution which aims merely at changing official policies and institutions with a view to an improvement in material conditions has little chance of genuine success. Without a revolution in spirit, the forces which had produced inequities of the old order would continue to be operative, posing a constant threat to the process of reform and regeneration. It is not enough merely to call for freedom, democracy and human rights. There has to be a united determination to persevere in the struggle, to make sacrifices in the name of enduring truths, to resist the corrupting influences of desire, ill will, ignorance, and fear.
