What we do know is that as we approach modern Hinduism over the last several hundred years, it did approach something that was more what you are born into. But we'll look at a little bit at the scripture and I'll leave it up to you to decide whether it was more of a social class or it was a class that you are born into. Now the four varnas that are described in the Vedas and in other Hindu scripture, at the top you have the Brahmins who are the priests and the teachers, not to be confused with the god Brahma or the ultimate reality Brahman. Next you have the Kshatriyas who are the warriors and rulers. And it's interesting that at least in Hindu society, the Brahmins were considered higher than the warriors, the rulers, the kings. After that you have the Vaishyas who are the farmers, the merchants. And then next, the Shudras, the laborers, those who worked in service to the other three classes.
