The Sai Satcharitra mentions several instances of devotees being cured of scorpion stings. Could you narrate a few of these stories and explain their common theme?

Chapter 33 of the Sai Satcharitra provides multiple accounts of devotees being cured of scorpion stings, all highlighting the power of faith in Sai Baba. When Narayanrao's friend was stung, simple incense ash applied with the belief that it was Udi provided immediate relief. In a footnote, another story describes Bapusaheb Jog being stung and going to Baba, who simply said, "It will be alright, go!" The pain vanished before he even left the compound. A third story tells of a Jyotishi Buwa who, after being stung, applied Udi and continuously chanted Baba's name, which stopped the pain and cemented his faith. The common theme is that whether through Udi, a simple word, or even a substitute for Udi, unwavering faith in Baba is the key to receiving His protection and blessings.
