Could you elaborate on the story of Khimji Lalji Joshi's daughter and how she was cured?

Chapter 33 details this healing in a footnote. Khimji Lalji Joshi's daughter had been ill for many days and became so weak that her hands and feet were like twigs and she could not walk. Her mother first took Udi from a devotee's house, which gave her some immediate relief. Later, the family took the daughter to Shirdi, where she had to be carried and seated near Sai Baba. Maharaj applied Udi to her and blessed her. Remarkably, within two to four days, she started walking on her own. When she still had some trouble getting up and sitting down, she complained to Baba, who then gave her a fruit to eat, which completely removed that remaining difficulty.
