Bali deaths: cleansing ceremony held in Noelene Bischoff and daughter Ivana's hotel room Balinese priest Mangku Made Wirasa carries out a cleansing ceremony at the room of Noelene Bischoff and her daughter Yvana. A HINDU priest has led prayers and offerings at the Bali hotel room where Sunshine Coast woman Noelene Bischoff and her teenage daughter Yvana fell critically ill. The prayers, known as a cleansing ceremony, were held today at the Padang Bai Beach Resort in a bid to restore positive energy and cleanse the resort of bad spirits. The ceremony, where traditional offerings in banana leaf baskets were laid, began at the hotel's small temple and then moved to room number seven, the room where Noelene and Yvana were staying when they became ill on January 3. The mother and daughter became seriously and suddenly ill late in the evening, after having dinner at the hotel restaurant and both passed away in the early hours of the next day. So far the cause of death is a mystery and autopsies are currently being conducted in Queensland. The sudden nature of their illness and subsequent deaths has left their family in shock. Noelene and Yvana Bischoff died under mysterious circumtances in Bali. The Padang Bai Beach Resort manager Giovanni Bareato said the cleansing ceremony was conducted on the auspicious day of a full moon in a bid to help the hotel's Balinese staff move on from the tragedy. A Balinese priest and the staff of Padangbai Beach Resort take part in the cleansing ceremony. "Tradition here in Bali is very, very important," Mr Bareato said of the reason for holding the ceremony. He said the ritual was done to help his staff and also as a form of respect for Noelene and Yvana. We are still in shock, as you can imagine. It was hard for everybody," Mr Bareato said. The prayers were led by Hindu priest, Mangku Made Wirasa and attended by about 25 of the hotel's staff, most of whom are Hindu, the dominant Bali religion. The cleansing ceremony was performed as a mark of respect for the mother and daughter, the manager of the resort says. Mr Wirasa said the ceremony was to cleanse any bad spirits from the room and to remove negative energy as well as prayers for the souls of Noelene and Yvana. "We pray for Noelene and Yvana even though we are a different religion," Mr Wirasa said. Room number seven had been closed off with police tape until the weekend and has now been cleaned and opened. The prayers were led by Hindu priest Mangku Made Wirasa and attended by the hotel staff. Hindu offering baskets were placed on a small coffee table and straw mat at the entrance and Mr Wirasa sat in front of the room as he prayed. Noelene, a highly-respected Sunshine Coast nursing manager, passed away in an ambulance as she was driven from the hotel to a clinic in the early hours of Saturday January 4. Her 14-year-old daughter Yvana was taken to hospital but also passed away several hours later. Initial suspicion focused on food poisoning or food allergy as being the cause of death but this is just speculation until the autopsies are complete. Police in Bali have said there was no obvious sign of a crime but say the investigation remains open pending the autopsy results.
