The Indian caste system is divided according to the structure of the body of Brahma(first god of the Trimurti, the trinity of Hinduism).
The four main castes are:
-The mouth (Brahmin) is the priests, philosophers and teachers;
-The arms (Kshatriya) are the military and government;
-The legs (Vaishya) are traders and farmers;
-Feet (Shudra) are the artisans, the workers and peasants.
The Dalits are called untouchables were not generated in the body of Brahma, so do not belong to castes. The Dalits are formed by those (and their descendants) who violated the codes of the caste to which originally belonged. They are considered unclean and therefore make the work more despicable.
Outside of the caste system, there are also the Adivasi (tribal people) and Mechhas (foreigners).
There is no individual salvation (Moksha) as the only person belongs to a caste to which she must complete loyalty. If the person violating the rules of their caste, the individual is expelled, becoming a dalit.
India is a country where equality does not belong to their culture.
The Westerners believe in equality ... and it is in human rights but can not come to India and say you are 'friends' of untouchables ...This is an example of a culture very different from the West.
