What was the thought process that led the family of the ailing boy to visit Shirdi, as described in Chapter 34?

According to Chapter 34, the family's decision to visit Shirdi was born out of complete desperation after all other avenues had failed. They had exhausted every medical treatment for the boy's bone-cyst, and their prayers to various deities had also gone unanswered. It was at this point they heard of a famous saint, Sai Maharaj, in Shirdi, who could supposedly heal diseases by his sight and whose Udi could cure incurable ailments. Viewing this as their "last resort," they decided to try it, thinking, "What is there to lose in gaining this experience?" This mindset shows they approached Sai Baba only after worldly remedies had proven entirely ineffective.
