The religious word for caste is 'varna' each has certain duties and rights. Each must only work in the occupations in which they are allowed, each must only eat a certain diet. To try to change is to invite bad karma and ruin your chances for improvement in the next life.
Each Varna consists of many communities called Jats. Each Varna does consist of different Jats but many of these Jats break up into more communities and each such community refers to itself as different or unique Jat. There are different reasons for these different communities within each Jat.
All the Jats accept that the Brahman Varna is the highest Varna in the hierarchy and the untouchables are outcast and lowest in the hierarchy. But most of the Jats in different Varnas claim to be superior and higher than other Jats. Some of the Jats as stated earlier break up into smaller communities or Jats. In these Jats that break up into different communities, there are communities that look at themselves as superior or higher in hierarchy than other communities. Among the Brahman Varna, there are Jats that consider themselves as superior than other Brahman Jats. Some of the Brahman Jats break up into smaller communities, and between these communities within the Jat there also exist a hierarchy.
Among the outcast there was also the superior status phenomenon in which one outcast Jat considered itself as superior and did not have physically contact with other outcast Jats which it considered as inferior. For example the Mahars in west India considered themselves superior than Dhed and they did not mingle with the Dheds.
Brahmins, the highest caste, were scholars and priests, while Kshatriya were warriors, rulers, and landlords. Vaisya were merchants, while Sudra were manual laborers. Beyond the four Varnas are the Untouchables or Dalit, and the system also has a space for outsiders and foreigners who do not conform with the system.
The Caste System has been illegal in India for more than fifty years, but it continues to shape people’s lives. The Indian government has provided the Harijan a term now popularly used in place of untouchable, with specific employment privileges, and granted them special representation in the Indian parliament. Despite such measures, the Harijan continue to have fewer educational and employment opportunities than Indians from higher castes.
