tjuringa

“On the other hand, if you smashed or lost your tjuringa, you were beyond the pale, and had lost all hope of ‘returning.'  of one young layabout in Alice, I heard it said, 'He hasn’t seen his truringa.  He doesn’t know who he is.’”

– FromThe Songlinesby Bruce Chatwin

A 'Tjuringa’ is a sacred stone, on which is written the piece of the songline that belongs to a particular person.  These are stored in a safe place and it is up to the individual to protect their tjuringa and keep it safe, therefore, keeping that piece of the song safe.
