Can you summarize the different instances mentioned in the Satcharitra where Sai Baba cured scorpion stings?

Chapter 33 provides several remarkable accounts of Sai Baba healing scorpion stings, each highlighting a different aspect of His grace. In one story, Narayanrao's friend was healed when ash from an incense stick was applied with faith, acting as a substitute for Udi. In a footnote, we learn of Bapusaheb Jog, who was stung and went to Baba. Baba simply said, 'It will be alright, go!' and the pain vanished before he even left the mosque compound. A third instance involves a Jyotishi (astrologer) who was stung in Rahata; his severe pain only stopped after he applied Baba's Udi and continuously chanted His name, which in turn established his faith. These stories from Chapter 33 illustrate that healing could come from Udi, from Baba's mere words, or even from a substitute empowered by pure faith.
