How do the different healing incidents involving scorpion stings and fever in the text illustrate the workings of Sai's grace?

The provided text from Chapter 33 presents multiple instances of healing that highlight the versatile nature of Sai's grace. For instance, Bapusaheb Jog was cured of a scorpion sting merely by Maharaj's words, "It will be alright, go!" A Jyotishi Buwa, also stung by a scorpion, found relief by applying Udi and performing Nama Smarana. This contrasts with the story of Nana Chandorkar, who, lacking Udi, used roadside clay combined with a prayer to heal a devotee's daughter from a severe fever. While the scorpion sting stories show the power of Sai's direct word and the application of actual Udi, Nana's story powerfully demonstrates that deep faith can empower even a substitute, proving that Sai's grace is not limited by physical objects or proximity.
