Marriage is an ancient institution existing in almost every society around the world. Two individuals come together to form the union of marriage, which gives rise to a family, which further forms the society, which ultimately forms the nation. Thus, the institution of marriage can be said to be the very foundation block of a nation. Being the foundation block, it could be used to integrate the masses by eliminating the differences. Little steps have been taken in this direction by the legislature and socio-religious institutions.

Since religious and communal conflicts are on the rise in present times in India, it seems to be the right time to explore this dimension.
