Why did the family of the boy with the bone-cyst decide to go to Shirdi? What was their mindset?

According to Chapter 34, the family's decision to go to Shirdi was born out of complete desperation. The boy's ailment, a bone-cyst, had proven incurable by any medical means, and the family was distressed watching him suffer. After exhausting all medical options and even finding no help from worshipping their family deities, they heard about a famous saint, Sai Maharaj of Shirdi. They were told that his Udi could cure incurable ailments and decided to try this as their "last resort," thinking, "What is there to lose in gaining this experience?" Their mindset was one of seeking refuge with total devotion, hoping that this final path might avert the calamity they were facing.
