How did the events leading up to Shaka year 1840 seem to confirm Baba's prophecy about Tatya?

The accuracy of Sai Baba's words, described as being etched in stone, became apparent as the foretold time approached. Chapter 42 recounts that Baba made the prophecy about Tatya's death two years in advance. Just as Baba had promised, Ramchandra Patil, who had been on his deathbed, recovered. The secret of the prophecy was kept from Tatya but shared with Bala Shimpi, causing both men great worry. As the days were counted, the Bhadrapad month of Shaka 1840 ended, and the prophesied month of Ashvin began. Precisely at this time, Tatyaba fell ill with a fever and was confined to his bed, making it seem as though Baba's prediction was unfolding exactly as he said it would.
