Thanks for such great information about history of the Balkans and Ottoman Empire. I don't know about Sufi culture (Islam in India?), but we probably (ourselves) changed the word to be more fitting to our language.

And your signature communicates almost opposite message from mine signature! Why so? (tu parles Franšais?)

Czarograd - you mean Carigrad (car - Emperor, grad - town). The former Slavic name for Istanbul.
Trazim da je uchim bosanskom - you first need Serbian-Latin keyboard I think you wanted to say - Učim bosanski.
Au revoir!
