The activities of so intrepid a people as the Sindhus or Hindus could no longer be kept cooped or cabined within the narrow compass of the Panchanad or the Punjab. The vast and fertile plains farther off stood out inviting the efforts of some strong and vigorous race. Tribe after tribe of the Hindus issued forth form the land of their nursery and led by the consciousness of a great mission and their Sacrificial Fire that was the symbol thereof, they soon reclaimed the vast, waste and but very thinly populated lands. Forests were felled, agriculture flourished, cities rose, kingdoms thrived,- the touch of the human hand changed the whole face of the wild and unkemp nature. But while these great deeds were being achieved the Aryans had developed to suit their individualistic tendencies and the demands of their new environments a policy that was but loosely centralised. As time passed on, the distances of their new colonies increased, and different settlements began to lead life politically very much centred in themselves. The new attachments thus formed, though they could not efface th old ones, grew more and more pronounced and powerful until the ancient generalizations and names gave way to the new. Some called themselves Kurus, others Kashis or Videhas or Magadhas while the old generic name of the Sindhus or Hindus was first overshadowed and then almost forgotten. Not that the conception of a national and cultural unity vanished, but it assumed other names and other forms, the politically most important of them being the institution of a Chakarvartin. At last the great mission which the Sindhus had undertaken of founding a nation and a country, found and reached its geographical limit when the valorous Prince of Ayodhya made a triumphant entry in Ceylon and actually brought the whole land from the Himalayas to the Seas under one sovereign sway. The day when the Horse of Victory returned to Ayodhya unchallenged and unchallengeable, the great white Umbrella of Sovereignty was unfurled over that Imperial throne of Ramchandra, the brave, Ramchandra the good, and a loving allegiance to him was sworn, not only by the Princes of Aryan blood but Hanuman, Sugriva, Bibhishana from the south-that day was the real birth-day of our Hindu people. It was truly our national day: for Aryans and Anaryans knitting themselves into a people were born as a nation. It summed up and politically crowned the efforts of all the generations that preceded it and it handed down a new and common mission, a common banner, a common cause which all the generations after it had consciously or unconsciously fought and died to defend.
