The ancient Varna system may or may not be in ideal practice, but it's a flexible natural order of mankind and makes sense even today. In fact many sections of society follow this naturally without any such stratification. The Varna quotient basically makes us who we are and what we do, in line with our inner callings. So what's our dominant mental temperament - your Varna quotient? Are we the kind of a "Braahmana", a "Kshatriya", a "Vaishya" or a "Shudra"? There is obviously no right or wrong answer. There is only a true answer that only we know of. That determines who we really are inside despite how we want to see ourselves as.
