Is Hindi really the ''National Language'' of India?

I am looking into the matter with a neutral perspective but even then the conclusion is the same. What has been told is not the complete truth. I will not tell it right away, because no one will believe it until it is proved to be so. So here you have your proof. Buy a copy of the Constitution of India.

The Constitution of India states as follows:
===========================================
PART XVII

OFFICIAL LANGUAGE

CHAPTER I.- LANGUAGE OF THE UNION

343. Official language of the Union.

1. The official language of the Union shall be Hindi in Devanagari script. The form of numerals to be used for the official purposes of the Union shall be the international form of Indian numerals.
2. Notwithstanding anything in clause (1), for a period of fifteen years from the commencement of this Constitution, the English language shall continue to be used for all the official purposes of the Union for which it was being used immediately before such commencement: Provided that the President may, during the said period, by order authorise the use of the Hindi language in addition to the English language and of the Devanagari form of numerals in addition to the international form of Indian numerals for any of the official purposes of the Union.
3. Notwithstanding anything in this article, Parliament may by law provide for the use, after the said period of fifteen years, of-
4.
1. the English language, or
2. the Devanagari form of numerals, for such purposes as may be specified in the law.
===========================================

Did you notice the bold characters. They are not written by me. It is the real and authentic text of the constitution. It says that Hindi is the ''Official Language of India''. Its is not the National Language. One has no right to interpret the word 'official' as 'national'. If it were to be the national language, it would have been mentioned as such, in the constitution. The notion of Hindi being the national language can be easily challenged.

So Hindi is nothing great from any other language in India. It has the same status as all other official languages. Even I accept that Hindi is the official language of India. I have no objection to learn Hindi or to speak it. However, nobody can force me to speak in Hindi, I stay in Maharashtra and the native language here is Marathi.
