Prahlad Jani, also known as "Mataji", (born Chunriwala Mataji, 13 August 1929) is an Indian sadhu. He claims to have lived without food and water since 1940, and says that the goddess Amba sustains him. In 2003, Sudhir Shah and other physicians at Sterling Hospitals, Ahmedabad, India observed Jani for 10 days. He stayed in a sealed room and was given only 100 millilitres of water to use as mouthwash each day. Doctors say that he passed no urine or stool during the observation, but that urine appeared to form in the bladder. A hospital spokesperson said that Jani was physically normal, but noted that a hole in the palate was an abnormal condition. The fact that Jani's weight dropped slightly during the 10 days has cast some doubt on his claim to go indefinitely without food.
