Unless you have passed at least class ten with Punjabi as a subject, your efforts, time and money may practically go waste.
The rights in Part III are not absolute, besides many points of law, there is also a question of intelligible differentia, the rights of the State of Punjab, the rights of livelihood of local native people of Punjab, the level of local unemployment in Punjab, which Punjab Government is Constitutionally duty bound to help.
Black's Law Dictionary 9th Edition -
Nation - A large group of people having a common origin, language, and tradition and usually constituting a political entity. When a nation is coincident with a state, the term nation-state is often used. Also termed nationality.
"The nearest we can get to a definition is to say that a nation is a group of people bound together by common history, common sentiment and traditions, and, usually (though not always. as, for example, Belgium or Switzerland) by common heritage. A state, on the other hand, is a society of men united under one government. These two forms of society are not necessarily coincident. A single nation may be divided into several states, and conversely a single state may comprise several nations or parts of nations." John Salmond, Jurisprudence 136 (Glanville L Williams ed., 10th ed. 1947).
Above clearly tells though we are a "Nation State"(a political and non natural entity) composed of numerous nations(States) as foundational units, we are not a natural nation in any real sense. This fact has also been acknowledged by Article 1 of the Constitution of India.
“There is no nation of Indians in the real sense of the world, it is yet to be created. In believing we are a nation, we are cherishing a great delusion. How can people divided into thousand of castes be a nation? The sooner we realise that we are not yet a nation, in a social and psychological sense of the world, the better for us.” - Dr. B. R. Ambedkar
