Describe the remarkable scene where Narayanrao's friend was stung by a scorpion and how he was cured without using actual Udi from Shirdi.

Chapter 33 recounts a powerful incident where a friend of Narayanrao was stung by a scorpion and was in severe agony. Narayanrao knew that Baba's Udi was the perfect remedy, but he could not find it anywhere. In his 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. In that moment of intense faith, he considered this ash to be Baba's Udi. He took a pinch, applied it to the sting while chanting Sai's name, and the result was miraculous. The pain subsided immediately, as if it were water flowing away, demonstrating that the power was in the devotee's faith as much as in the substance itself.
