Dravidian principles and cultural changes

It can be said that culture is the total development stage of human race. This culture evolves and travels over time from one generation to another. In this way, the 'Dravidian principle' has the basic principle that the culture found in human thoughts, beliefs, customs, rituals and ethnic lifestyles should be operated with rationality as the key. The 'Dravidian policy' is to put an end to the irrational act of Tamils forgetting their ethnic name due to the Aryan cultural invasion and giving preference to their caste name. Here, Periyar's Dravidian doctrines and Bharathidasan's concepts are presented and the data for the research paper is presented.
