India is an amazing land of great variety. It is the second-most populous country in the world (after China), with hundreds of languages spoken. Many of the languages descend from the ancient Indian language called Sanskrit, which plays a role similar to Latin in Europe. Most Indians are Hindu; there are also a large number of Muslims, Christians, and smaller numbers of followers of other religions. India is a land of great wealth and poverty; it is armed with nuclear weapons and has a space program, but also many areas of slums where people live in desperate poverty.

Hinduism is the third largest organized religion in the world, practiced by over 900 million people. About 800 million of those are in India. Nepal is actually the only country in the world where Hinduism is the official religion. Hinduism is based on four concepts. Dharma has to do with individual ethics. Samsara has to do with reincarnation. Karma has to do with cause and effect (good actions produce good results, for example). And Moksha is the Hindu idea of salvation. Hindus believe in a variety of different gods and goddesses.
India’s caste system is officially illegal, but you can still see it operating in some areas. In this system, people are born into one of four castes, or varnas. These are different social groups, each with different status. People are often limited in what they can do, who they can marry, where they can live, etc., by their caste. Sometimes people of one caste will not associate with people from another caste. There is a fifth group, the Untouchables (or Dalit), who are below all the others, are shunned by society, and restricted to the most menial jobs. In the picture you see a slum in India where many Dalits live.
