Here we go, instead of focusing on why we do not create our own culture, it's :what's Indian culture?" -- If it's made in India, it's Indian culture, if it's about India, It's Indian culture, Savvy?
Think about why we do not create Pakistani culture, that will be more useful than clubbing the indian.
pak culture will be similar to indin culure. Now before you all hyperventilate, please listen.
Pak like India has a number of states with differing cultures. LIke Punjabi, Sindhi, Pashtun etc. However to have a composite Pak culture the binding force has to come from modern happenings like cricket, older traditions, your poetry, with a dash of religion.
