I hav seen lot many cultures prevailing in India.As each state has its own culture and from the pre entries of mah bolgs we found that states are divided into regions and these regions are further divided to different culture... as taken J&K for an instance..J&K shows a variety of culture. And these all three regions Jammu , Kashmir and Ladakh's culture makes a unique culture which represents the state J & k.

The dance,music,lifestyle,cuisine,festivals...all are totally different but somewhere upto an extent we can say that yes other cultures prevailing in India are a bit similar..just get differentiated on the basis of different names given to them...

we can take for instance the dressing style here in Jammu ladies use to wear "salwar kameez with dupata" and we call it "dogri drees" but same dress wear by ladies of Punjab too...then it comes under "Punjabhi dress". So we can say that somewhere different culture shows similarities too...
