INFERENCE
Varna system of classification was based on the gunas of each individual, with the aim of creating highest quality professionals who were naturally best suited for each responsibility.
Procedure:
Topic of debate is "the merits and de-merits of a caste system based on gunas versus having a caste system based on birth."
Conclusion:
The Varana system of classification prescribed in the Bhagavad Gita is not based on birth of a person. Varna system was intended to be an economic system to achieve national excellence.
