Hindutva is the only binder which can galvanize the Indian nation towards progress and prosperity. In essence, nationalism is synergy. The effort of four Indians should yield the result equivalent to five or six of them. Most Christians and Muslims of India have a Hindu ancestry.
Their collective memory has not necessarily forgotten their castes. It is not uncommon to find a Catholic claiming himself to be a Brahmin and insisting on a Brahmin bride. Nor is it unusual to come across a Muslim who claims that he is a Rajput to indicate that he is not a convert from any other caste. The Bohras are forthright in their claim that all of them were converted from Brahmins.
