Who was Khimji Lalji Joshi, and what role did Sai Baba's Udi play in healing his daughter?

Khimji Lalji Joshi was a gentleman serving in a Punjab regiment in Palya, whose story is recounted as an example of Udi's glory. According to Chapter 33, his daughter had been ill for many days and became very weak, with her limbs like twigs. Her mother first obtained some of Maharaj's Udi, which provided immediate relief. The family then traveled to Shirdi, where the daughter, unable to walk, was carried to Sai Baba. Maharaj applied Udi to her and blessed her. Within a few days, she began to walk on her own. When she still had trouble getting up, Baba gave her a fruit to eat, which completely removed that difficulty as well.
