The painting depicts the Dreamtime Sisters (guardian spirits). Eastern Arrernte Aboriginal people from Central Australia call the spirits 'Irrernte-arenye'.

It is their role to guard special areas of land in particular sacred sites. Eastern Arrernte people have deep spiritual respect for the Dreamtime spirits. The blue patterned mounds represent the Dreaming sites, which are the areas the spirits protect.
