Prahlad Jani, a sadhu, spent ten days under strict observation by physicians in Ahmedabad, India, in 2003. The study was led by Dr Sudhir Shah, the same doctor who led the study of Hira Ratan Manek. Reportedly, during the observation, he was given only 100 millilitres of water a day to use as mouthwash, which was collected and measured after he used it, to make sure he hadn't consumed any. Throughout the observation, he passed no urine or stool, but doctors say urine appeared to form in the bladder, only to be reabsorbed.[29] However, despite Jani's claim to have gone without food for decades, Jani was not engaged in strenuous exercise during the ten-day trial, and longer trials were not recorded under similarly strict observation. Further, his weight did drop slightly during the 10 days, casting some doubt on his claim to go indefinitely without food. Jani claims a goddess sustains him through amrit that filters down through a hole in his palate.[29] The Indian Rationalist Association labels him a "village fraud".[30]
