Describe the family's plea to Sai Baba and his compassionate response as documented in Chapter 34.

As documented in Chapter 34, the parents of the suffering child arrived in Shirdi and immediately sought Sai Baba's darshan. With choked voices and folded hands, they prostrated at his feet and made a pitiful plea. They explained that they could not bear to see their son's suffering and felt they had no other way out. They begged Sai Samarth to place his protective hand on their son's head and remove the ailment, having come to him with total devotion. In response, Sai, described as the embodiment of compassion, reassured them completely. He told them to be worry-free and gave them his sacred Udi, instructing them to smear it on the wound, promising that the calamity would be averted.
