CASTE

The doctrine of the caste system is believed to have been explained by Manu, a learned Bramhin in the days of yore. In the text known as Manusmriti prepared by him, categories and levels of all men are fixed right from their birth based on the clan or the caste they are born into.  Assignment of job, way of life and accountabilities and everything relevant to the person has been prescribed accordingly in the text. The four main castes are the following (of which there are many more divisions and subdivisions):

Bramhana: The priestly caste

Ksetriya: The caste of warriors and rulers

Vaisya: The caste of farmers and traders etc.. 

Sudra: The menial caste

According to this Hindu doctrine, all men originated from the various parts of the body of Bramha, the creator. So, Bramhins originated from his head whereas Kshetriyas, Vaisyas and Sundras are originated from his arms, thighs and feet respectively. So the higher castes are supposed to be served by the lower castes. Although, this type of classification is highly debated and generally condemned or differently interpreted these days, the social structure and its effects are still very much in existence. However, discrimination in the ground of caste is illegal in Nepal.
