Should some States be governed by special provisions? Does this create resentment among other States? Does this help in forging greater unity among the regions of the country?

Some States feel resentment among other States if some States are granted the special
provision by the constitution:
 Under Article 370, Jammu and Kashmir enjoys more autonomous powers rather
than the other States.
 Most of the special provisions pertain to the north-eastern states like Arunachal
Pradesh, Mizoram, Assam, Nagaland, etc. due to sizeable indigineous tribal
population with a distinct history and culture, which they wish to retain under Article
371.

 Even some hill States like Himachal Pradesh and some other States like Maharashtra, Goa, Sikkim, Gujarat, Andhra Pradesh also enjoy some special provisons.  Some differences in case of division of the part of Uttar Pradesh in Uttarakhand, where the people can purchase agricultural land in Uttar Pradesh also but the people from Uttar Pradesh cannot purchase in Uttarakhand, createsresentment among the poeple.  Hence, the other States demand the division of power in a common manner to all.  This forges unity in diversity due to single citizenship and single judiciary in country.
