How did Narayanrao Jaani manage to cure his friend's scorpion sting even though he couldn't find any of Baba's Udi?

As detailed in Chapter 33, when Narayanrao Jaani's friend was in severe agony from a scorpion sting, Narayanrao could not locate any of Baba's Udi. In desperation, he prayed compassionately to a picture of Sai Baba. He then noticed the ash from burnt incense sticks that had fallen at the bottom of the picture frame. In that moment, he considered this ash to be Udi. Taking a pinch of it and muttering the Sai Nama mantra, he applied it to the sting. The scripture states that the pain immediately subsided, demonstrating that the power was in the faith and feeling with which the act was performed, rather than the substance itself.
