He claims to have lived without food and water since 1940, and says that the goddess Amba sustains him. Prahlad Jani, says that he is surviving by chanting mantras and by meditating for goddess Amba.
Prahlad Jani has been kept under observations 2 times to know the medical reason behind his claim and also to prove his claim of living without food or water from 1940. He believes that the goddess Amba provides him with a water like sustainable liquid inside his body to keep him alive.
Till now 2 observational studies has been made, one in 2003 and another in 2010 to prove his claim or to deny it. Many expert neurologists monitored Jani and they were surprised by the result. The experts confirmed Jani's ability to survive without food or water but the claim was not proven due to many allegations relating to the procedure of tests conducted.

The Moore family consisted of parents Josiah B. (aged 43), Sarah (née Montgomery) (39), and their four children: Herman Montgomery (11), Mary Katherine (10), Arthur Boyd (7), and Paul Vernon (5). An affluent family, the Moores were well-known and well-liked in their community.[1] On June 9, 1912, Katherine Moore invited Ina Mae (8) and Lena Gertrude Stillinger (12) to spend the night at the Moore residence. That evening, the visiting girls and the Moore family attended the Presbyterian church where they participated in the Children's Day Program, which Sarah Moore had coordinated. After the program ended at 9:30 p.m., the Moores and the Stillinger sisters walked to the Moores' house, arriving between 9:45 and 10 p.m.

Unfortunately for the six members of the Moore family, we are entirely sure that what happened to them actually happened. And what happened is particularly gruesome. At some point between the evening of June 9, 1912, and early morning of June 10, 1912, the family and two house guests were bludgeoned to death in their rural Iowan home. All eight victims, including six children, suffered severe head wounds from an axe. And the murderer is still on the loose.
Well, possibly not. They’re probably elderly and/or dead by now, but still, they got away with it. The affluent family had a pretty good social standing in the Villisca community, friendly with all their neighbours. If they weren’t, then they might not have been discovered so quickly; on member of the town thought it strange they hadn’t appeared to do their morning chores, as they did every day outside the house at 7am sharp, and it’s that neighbour who raised the alarm of the horrific scenes inside.
The killer – or killers – had methodically gone from room to room, killing each member of the household in their sleep with an axe – or axes. There have been numerous suspects, from a hobo passing through town to a travelling minister to an elaborate conspiracy theory involving an Iowa state senator hiring a serial killer to do the family in, because the elder Moore had stolen business by opening a more successful tool store than the senator had. The reverend was tried twice, and acquitted each time.
The Villisca Axe Murder House, as it has been delightfully redubbed, has since been renovated and is now a tourist attraction, as a company gives guided tours and talks up the possibility of the house being haunted. It probably isn’t haunted, but the town still is, because despite being such a grizzly murder and in such a small town, the killings have never been solved.

Suspects
Frank Jones was a Villisca resident and an Iowa State Senator. Josiah Moore had worked for Frank Jones at his implement store for many years before leaving to open his own store. Moore reportedly took business away from Jones, including a very successful John Deere dealership. Moore was rumored to have had an affair with Jones’ daughter-in-law, though no evidence supports this
At the inquest, it was reported that Sam Moyer (Josiah's brother-in-law) often threatened to kill Josiah Moore; however, upon further investigation, Moyer's alibi cleared him of the crime.[5]
