What motivated the family from Malegaon to travel to Shirdi, despite having access to modern medicine?

As detailed in Chapter 34, the family's motivation to visit Shirdi stemmed from desperation and hope. All conventional medical remedies had been exhausted on the doctor's nephew, and even expert surgeons felt helpless against his bone-cyst. When all treatments failed, relatives first suggested worshiping deities. Subsequently, they heard word of a famous Avaliya (saint) in Shirdi, Sai Maharaj, who could supposedly heal diseases just by his sight. They decided to try this "last resort," hoping that if he applied Udi with his own hand, the incurable disease might perish.
