According to the source, how did Sai Baba's prophecy regarding Tatya unfold, and what did it reveal about Baba's words?

The prophecy's unfolding demonstrated the absolute certainty of Baba's words. As detailed in Chapter 42, Ramchandra Patil recovered from his illness just as Baba had promised. The prediction about Tatya was kept secret, whispered only to Bala Shimpi. As the prophesied time—the month of Ashvin in Shaka year 1840—drew near, Tatyaba fell ill with a fever and was confined to his bed. This turn of events, happening exactly as foretold two years earlier, highlighted what the text calls the "wonderful accuracy of Baba's words," which were considered to be as permanent and unchangeable as if they were "etched in stone."
