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. And we'll talk a little bit more about how this may or may not be changing. Now to see the basis of the varna system in scripture, I will start with this quote from the Rig Veda. Now this is from the Purusha Sukta, and Purusha in the Vedas, you can view as this cosmic being, but they anthropomorphize this being, making it seem or making it an analogy with a human body.
