1. They serve as a reminder to the citizens that while enjoying their rights, they should also be conscious of duties they owe to their country, their society and to their fellow citizens.
2. They serve as a warning against the anti-national and anti-social activities like burning the national flag, destroying public property and so on.
3. They serve as a source of inspiration for the citizens and promote a sense of discipline and commitment among them.
4. They help the courts in examining and determining the constitutional validity of a law.
