This miny'tji represents Rulyapa, the rough saltwater country between Nhulunbuy and the large island of Dhambaliya (Bremer Island), ballooning up from the secret depths, around the sacred rock Manhala, which can be a manifestation of Daymirri.

Daymirri is an enigmatic giant sea being (perhaps a whale shark) that according to Rirratji'u and Djambarrpuy'u clan manikay (sacred song) pertains to the saltwater country close to Yirrkala.

The dome-shaped rock Manhala exposes itself at the low tide, above the ra (tide marks), bleached white, a patina of brine and weather. Manhala is one of many names given to the rock. Djambarrpuy'u and Rirratji'u clans have many 'deep' names that are intoned by the ritual specialists at the culmination of appropriate ceremony.

The sea surrounding the rock, its tidal movements, differing states and the effect it had on Yolgnu visiting this site in Ancestral times is all recorded in the sacred song. As are all the totemic species of marine life that have these ancestral connections to the Rirratji'u and Djambarrpuyu.

Often painted in this design is Daymirri the whale, Balpa the rock cod, Djumbarr the red emperor, Garrarrpa, the king brown snake and Mutjalanydjal, the dolphin. All of these things and all of their meanings are implied simply by the presence of the miny'tji (sacred clan design) for the water. It's not just Manhala and the power associated with deep-seated knowledge that makes this area both sacred and dangerous to those entering without authority. There are three other rocks in the area of same qualities but these ones; Wakwakbuy, Mul'uwuy and Dharrpawuy, are submerged.
