The concept of the Dreaming is inadequately explained by English terms, and difficult to explain in terms of non-Aboriginal cultures. It has been described as "an all-embracing concept that provides rules for living, a moral code, as well as rules for interacting with the natural environment ... provides for a total, integrated way of life ... a lived daily reality". It embraces past, present and future. Another definition suggests that it represents "the relationship between people, plants, animals and the physical features of the land; the knowledge of how these relationships came to be, what they mean and how they need to be maintained in daily life and in ceremony". According to Simon Wright, ""jukurrpa" has an expansive meaning for Warlpiri people, encompassing their own law and related cultural knowledge systems, along with what non-Indigenous people refer to as ‘dreaming’".
