What were the specific events that occurred in the two weeks leading up to Sai Baba's Mahasamadhi, and how did the timing coincide with a Hindu festival?

In the final days before His passing, Sai Baba made a specific arrangement to prepare for His departure. As detailed in Chapter 44 of the Shri Sai Satcharitra, Baba knew His end was near and requested to listen to the Ramayana being read by a Brahmin. He engaged in this with focused contemplation continuously for fourteen days and nights. The chapter explicitly states that as these two weeks of listening to the Ramayana were completed, the day of the festival Vijayadashami arrived, and it was on this auspicious day that Baba attained the state of bodilessness, or Mahasamadhi.
