What happened when Narayanrao Jaani's friend was stung by a scorpion, and how was Sai Baba's Udi involved, even when it was missing?

According to Chapter 33, when a friend of Narayanrao Jaani was in severe agony from a scorpion sting, Narayanrao could not find the actual Udi from Baba. In this moment of desperation, he turned to a picture of Sai Baba and prayed compassionately. He then noticed the ash from burnt incense sticks that had collected at the bottom of the picture frame. Considering this ash as Udi in that moment, he took a pinch, applied it to the sting while chanting the Sai Nama mantra, and the pain immediately subsided. This incident shows that the faith and feeling behind the act were paramount.
