What is the central message that Chapter 34 of the Shri Sai Satcharitra seeks to convey about Udi?

The central message of Chapter 34 is the profound and miraculous glory of Sai Baba's Udi. The chapter explicitly states that it is a continuation of the previous chapter's description of Udi's greatness. It uses the compelling story of the Malegaon doctor's nephew, who was cured of an incurable bone-cyst, as a prime illustration. The narrative demonstrates that Udi is not merely ash but a vessel of Sai Baba's grace and healing power, capable of succeeding where all medical science fails. By showing how smearing the Udi from Sai's hand completely uprooted the painful disease, the chapter reinforces the theme that with faith in Sai, his Udi serves as a potent remedy for physical ailments and a symbol of his divine protection for devotees.
