I heard a story about a scorpion sting being healed without using actual Udi. Can you explain what happened?

Yes, Chapter 33 recounts a remarkable incident involving a friend of Narayanrao who was stung by a scorpion and was in severe agony. When Narayanrao couldn't find his container of Baba's Udi, he turned to a picture of Baba in desperation. He noticed the ash from burnt incense sticks that had fallen at the bottom of the picture frame. In that moment of crisis, he considered this ash to be Udi, prayed compassionately, and applied a pinch to the sting while chanting Sai's name. The text describes that the pain subsided immediately, as if water were flowing away, demonstrating the immense power of faith combined with prayer.
