How did Sai Baba's Udi and Aarti miraculously help Nana Chandorkar's daughter during her difficult childbirth?

Sai Baba's divine grace was demonstrated powerfully through the timely arrival of his Udi and Aarti. Chapter 33 recounts that just as Ramgir Buwa arrived with the sacred items from Shirdi, Nana Chandorkar's daughter was in extreme distress due to a difficult labor. A fire ritual was even being arranged to avert the crisis. In that critical moment, Nana administered the Udi to his daughter and began singing the Aarti. The effect was immediate and miraculous. The text states that a moment had hardly passed before news came that as soon as the cup of Udi touched her lips, she found relief and experienced a smooth, easy delivery, ending the family's anxiety.
