According to the source, what was the family's reasoning for deciding to travel to Shirdi?

As described in Chapter 34, the family's decision to travel to Shirdi was a final act of desperation after all other options had failed. Having exhausted every available medical treatment for the boy's bone-cyst, they heard about a famous Avaliya (saint) in Shirdi, Sai Maharaj. Word reached them that this great saint could heal diseases with just his sight and that incurable ailments would perish if he applied Udi with his own hand. Their reasoning was, "What is there to lose in gaining this experience?" They viewed the journey as a "last resort" and their only remaining hope to avert the calamity. This thought process, detailed in Chapter 34, led the parents to pack their things and travel to Shirdi for Sai's darshan.
