Why did the family of the sick child in Malegaon decide to go to Shirdi to see Sai Baba?

The family decided to visit Sai Baba in Shirdi as a final act of desperation after all other remedies failed. As detailed in Chapter 34, the boy's bone-cyst could not be cured by any medical treatment, leaving the family worried and distressed. Having reached the limit of medical options, word reached them of a famous saint, or Avaliya, in Shirdi named Sai Maharaj. They heard that he could heal diseases merely by his sight and that his Udi could cure even incurable ailments. Believing this to be their last resort and a final way to potentially avert the calamity, they decided to travel to Shirdi to seek his help.
