But the Indian definition of secularism is limited to the coexistence of many religions which is incomplete because some religions can still be marginalised as they are.

The invention of an Aryan race in nineteenth century Europe was to have, as we all know, far-reaching consequences on world history. Its application to European societies culminated in the ideology of Nazi Germany. Another sequel was that it became foundational to the interpretation of early Indian history and there have been attempts at a literal application of the theory to Indian society. Some European scholars now describe it as a nineteenth century myth. But some contemporary Indian political ideologies seem determined to renew its life. In this they are assisted by those who still carry the imprint of this nineteenth century theory and treat it as central to the question of Indian identity. With the widespread discussion on 'Aryan origins' in the print media and the controversy over its treatment in school textbooks, it has become the subject of a larger debate in terms of its ideological underpinnings rather than merely the differing readings among archaeologists and historians.
