What was Sai Baba's response and specific instruction to the family of the boy with the bone-cyst?

In Chapter 34, after the parents from Malegaon pleaded for their suffering son, Sai Baba's reaction showcased his divine compassion. The text refers to him as the "embodiment of compassion" who immediately reassured the worried family. He told them that those who seek shelter in his Masjid shall never face downfall. He then gave them a simple yet profound instruction to address the incurable ailment. Baba's exact words were, "Now you remain worry-free. Take this Udi and smear it on that wound." This response underscores the chapter's theme of Udi's supreme power and Baba's role as a protector for those who seek refuge in him.
