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. Now you also had and have people who are outside of these four different classes. Today they refer to themselves as Dalits, which means the oppressed, but sometimes they've been referred to as untouchable. And that's because in traditional Hindu society, many of these people weren't even able to enter temples, they were discriminated against, they didn't have access to resources, they weren't even allowed to shake hands or make physical contact with other members of Hindu society.
