And, therefore, if you succeed in the attempt to throw off your religion and take up either politics, or society, or any other things as your centre, as the vitality of your national life, the result will be that you will become extinct. To prevent this you must make all and everything work through that vitality of your religion. Let all your nerves vibrate through the backbone of your religion. I have seen that I cannot preach even religion to Americans without showing them its practical effect on social life. I could not preach religion in England without showing the wonderful political changes the Vedanta would bring. So, in India, social reform has to be preached by showing how much more spiritual a life the new system will bring; and politics has to be preached by showing how much it will improve the one thing that the nation wants — its spirituality.
