Thus India is working upon the world, but one condition is necessary. Thoughts like merchandise can only run through channels made by somebody. Roads have to be made before even thought can travel from one place to another, and whenever in the history of the world a great conquering nation has arisen, linking the different parts of the world together, then has poured through these channels the thought of India and thus entered into the veins of every race. Before even the Buddhists were born, there are evidences accumulating every day that Indian thought penetrated the world. Before Buddhism, Vedanta had penetrated into China, into Persia, and the Islands of the Eastern Archipelago. Again when the mighty mind of the Greek had linked the different parts of the Eastern world together there came Indian thought; and Christianity with all its boasted civilisation is but a collection of little bits of Indian thought. Ours is the religion of which Buddhism with all its greatness is a rebel child, and of which Christianity is a very patchy imitation.
