Thus is was political and national necessity that was at once the cause and the effect of the decline of Buddhism in India. Buddhism had its geographicalcentre of gravity nowhere. So it was an imperative need to restore at least the national centre of gravity that India had lost in attempting to get identified with Buddhism. When the nation grew intensely self-conscious as an organism would do and was in direct conflict with non-self it instinctively turned to draw the line of division and mark well the position it occupied so as to make it clear to themselves where they exactly stood and to the world how they were unmistakably a people by themselves-not only a racial and national, but even a geographical and political unit. On the southern side of our country the natural and sanctified. The frame work of the deep and boundless seas in which our southern peninsula is set is almost poetical in its grace and perfection. The Samudrarashana had pleased the eyes of generations of our poets and patriots. But on the north-western side of our nation the commingling of races was growing rather too unceremonious to be healthy and our frontiers too shifty to be safe. Therefore it would have been a matter of surprise if the intense spirit of self assertion that had found so benign an asylum under the patronage of the Mahakal of Ujjain had not made our patriots turn to this pressing necessity of drawing a frontier line for us that would be as vived as effective. And what could that line be but the vivacious yet powerful stream-the River of rivers-the ‘Sindhu’ ? The day on which the patriarchs of our race had crossed that stream they ceased to belong to the people they had definitely left behind and laid the foundation of a new nation were reborn into a new people that, under the quieting star of a new hope and a new mission, were destined by assimilation and by expansion to grow into a race and a new polity that could only be most fittingly and feelingly described as Sindhu or Hindu.
