What sequence of events led the parents of the suffering child to seek out Sai Baba in Shirdi, as detailed in Chapter 34?

Chapter 34 explains that the parents of the child suffering from a bone-cyst reached a point of complete desperation. After all medical remedies, including those from expert surgeons, failed, their relatives first suggested worshiping deities, which also proved ineffective. It was only after exhausting these options that word reached them of a famous saint, or Avaliya, in Shirdi known as Sai Maharaj. They heard stories that he could heal diseases just by his sight and that Udi applied by his hand could cure incurable ailments. Viewing this as their last resort, the parents packed their belongings and traveled to Shirdi, eager for Sai's darshan to try this final remedy.
