Whenever there has been a great conquering race, bringing the nations of the world together..., making roads and transit possible, immediately India arose and gave her quota of spiritual power to the sum total of the progress of the world. This happened ages before Buddha was born, and remnants of it are still left in China, in Asia Minor, and in the heart of the Malayan Archipelago. This was the case when the great Greek conqueror united the four corners of the then known world; then rushed out Indian spirituality, and the boasted civilisation of the West is but the remnant of that deluge. Now the same opportunity has again come; the power of England has linked the nations of the world together as was never done before. English roads and channels of communication rush from one end of the world to the other. Owing to English genius, the world today has been linked in such a fashion as has never before been done. Today trade centres have been formed such as have never been before in the history of mankind. 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.
