And immediately, consciously or unconsciously, India rises up and pours forth her gifts of spirituality; and they will rush through these roads till they have reached the very ends of the world. That I went to America was not my doing or your doing; but the God of India who is guiding her destiny sent me, and will send hundreds of such to all the nations of the world. No power on earth can resist it. This also has to be done. You must go out to preach your religion, preach it to every nation under the sun, preach it to every people. This is the first thing to do. And after preaching spiritual knowledge, along with it will come that secular knowledge and every other knowledge that you want; but if you attempt to get the secular knowledge without religion, I tell you plainly, vain is your attempt in India, it will never have a hold on the people. Even the great Buddhistic movement was a failure, partially on account of that.
