Describe the events leading up to Vijayadashami of Shaka 1840, focusing on the illnesses of both Tatya Patil and Sai Baba.

The events leading up to Vijayadashami of Shaka 1840 were filled with anxiety and foreboding for those who knew of Sai Baba's prophecy. As Chapter 42 recounts, two years after the prediction was made, the month of Ashvin began, and Tatyaba fell ill with a fever, taking to his bed. His physical agonies were unbearable, yet his mind remained fixed on Baba. Concurrently, an extraordinary thing happened: as Tatya's illness worsened, "Baba felt tremors," and his own groaning and gasping increased day by day. His own illness became uncontrollable. As the predicted day of Dashami finally arrived, both Ramchandra Patil and Bala Shimpi, who knew the secret, grew terrified as Baba's words seemed to be coming true with Tatya's pulse weakening.
