How did Sai Baba react when the parents of the sick child pleaded with him for help in Chapter 34?

When the parents of the child suffering from a bone-cyst approached Sai Baba, they were overcome with emotion. As described in Chapter 34, they prostrated at his feet, narrated their son's suffering with choked voices and pitiful faces, and pleaded for his help. Sai Baba, who is referred to as the 'embodiment of compassion,' responded with immediate reassurance. He told the worried parents to be 'worry-free' and promised that those who seek shelter in the Masjid shall never face downfall. He then gave them the simple instruction to take his Udi and smear it on the wound, showing his calm and confident grace in the face of their distress.
