What was the significance of linguistic reorganization of Indian states to the nation building?

In the initial years it was felt that linguistic states may foster separatism and create pressures on newly founded nation. But India considered democracy and federalism by making a favor to linguistic states only: 

1. Linguistic states enhanced democratic practices. 

2. Linguistic states reduced separatist attitude by accepting the regional linguistic claims of all regions. 

3. Linguistic reorganization provided a uniform base to the nation and strengthened unity of nation. 

4. Linguistic states promoted the principle of unity in diversity, a distinct feature of nation.
