south indian language, culture and civilization, dravidian civilization, is important for many of linguists, anthropologists and archaeologists. so, they are trying to find the origins of it. today, the scholars of civilizations try, however, to find any connection between dravidians culture and their own language and culture. so, they attempt to study in this field. it is clear that the cultural, religious and linguistic and even traditional similarities of dravidians in different parts of the world could be a better reason for serious study of this civilization. they didn’t leave any systematic thing about their own culture and rites, coherent philosophical system, substantial literature, manuscripts and written sources to show their religion. but, we can obtain information about them from the stories and legends that are observed in the festivals and holy books and indian religions.
