The three classes, Brahmins, Kshatriyas, and Vaishyas, although not very happy in their mutual relationship, managed to work by compromise. The Brahmin flattered the Kshatriya, and both let the Vaishya live in order to be able to live upon him. But the three agreed to beat down the Shudra. He was not allowed to acquire wealth, lest he should be independent of the three [higher] Varnas. He was prohibited from acquiring knowledge, lest he should keep a steady vigil regarding his interests. He was prohibited from bearing arms, lest he should have the means to rebel against their authority. That this is how the Shudras were treated by the Tryavarnikas is evidenced by the Laws of Manu. There is no code of laws more infamous regarding social rights than the Laws of Manu. Any instance from anywhere of social injustice must pale before it.
