Describe the scene of the parents' plea to Sai Baba when they arrived in Shirdi regarding their suffering child.

As detailed in Chapter 34, upon reaching Shirdi, the desperate parents of the boy with the bone-cyst immediately sought Sai Baba's darshan. Overcome with emotion, they bowed at his feet and prostrated themselves before him. With choked voices, folded hands, and pitiful faces, they narrated their child's immense suffering and their own exhaustion. They pleaded with Sai Samarth, expressing how they could no longer bear to see their son's pain and saw no other way out. They asked him to place his protective hand on the boy's head and remove the ailment. In response to their heartfelt petition, Sai, the embodiment of compassion, reassured them, telling them to be worry-free and to apply his Udi to the wound.
