"Human problems are more psychological than materialistic. This is not only true of individual behaviour, but in mass action also. A suggestion from a leader sparks off a revolution. Material circumstances help mass action, but in themselves do not raise action. The conditions of untouchability and of poverty in India, especially at the time of famine in Bengal in 1945-46, when thousands of destitute died of sheer hunger in the streets of Calcutta City, are such as would provoke an immediate revolution. But the revolution does not come off in the Indian masses. The reason is clear. In India there are revolutionary circumstances, but there is no revolutionary consciousness among the people. If the revolutionary consciousness is present, people would revolt against any injustice on the slightest pretext. And consciousness is essentially psychological."
