Hindi Sahitya Ka Itihas- Acharya Ramchandra Shukla

A Hindu, to sum up the conclusions arrived at, is he who looks upon the land that extends from Sindhu to Sindhu, from the Indus to the seas, as the land of his forefathers, his pitrabhu, who inherited the blood of that race whose first discernible source is traced to the Vedic Saptasindhus, which, on its onward march, assimilated much that was incorporated and ennobling. The Hindus, who inherited and claimed as their own the culture of that race, as expressed chiefly in their common classic language, Sanskrit, and represented by a common history, a common literature, art and architecture, law and jurisprudence, rites and rituals, ceremonies and sacraments, fairs and festivals, and who, above all, address this land, this Sindhustan, as their punyabhu, as the holy land, the land of their saints and seers, of godmen and gurus, the land of piety and pilgrimage. These are the essentials of Hindutva – a common rashtra, a common jaati, and a common sanskriti. All these essentials could best be summed up by stating in brief that they are Hindu to whom Sindhustan is not only a pitrabhu but also a punyabhu.
