All Australian Aboriginals believe in the Dreamtime. Each group and each person has their own stories and traditions. In Central Australia, the Pitjantjatjara call it the Tjukurpa. The Tjukurpa provides the answers for questions about life. It also gives the rules for behaviour and how to live together. It explains the complex relationship between the people, animals, plants and the land. It teaches the how and why the land is to be looked after. It provided the information about what could be eaten, the rules of marriage, of growing up and the rituals of death. Some parts of the Dreamtime are only known to those who have inherited the right to the knowledge.
