Examine the concept of three tiers government of Indian federalism

Federal governments have two or more tiers of governments. For a small country like Belgium two tiers are very much applicable but a vast country like India cannot be run only through these two tiers. States in India are as large as independent countries of Europe, many of these states are internally very diverse.
Hence, federal power sharing in India needs another tier of government, below that of state government. Thus resulted a third-tier of government, called ‘local government’.
