What is the utility of the term Fundamental Duties being a part of the Indian Constitution?

The Constitution which came into force on 26th January, 1950 did not contain the provision of Fundamental Duties. It was inserted in our Constitution by 42nd amendment of theConstitution in 1976. The Fundamental Duties are intended to serve as a constant reminder to every citizen that while the constitution specially conferred upon him certain Fundamental Rights, the citizens are also required to observe certain basic norms of democratic conducts and behaviour. For the first time a set of 10 Fundamental Duties of citizens have been enumerated by this amendment.
