What specific spiritual practice did Sai Baba undertake in the two weeks just before his Mahasamadhi, as narrated in Chapter 44?

Chapter 44 of the Sai Satcharitra details a specific and significant spiritual observance by Sai Baba in His final days. The text explicitly states that, knowing His end was approaching, Baba arranged to listen to the Ramayana being read aloud by a Brahmin. This was an intense and dedicated practice, as He listened with "focused contemplation for fourteen days and nights." The chapter directly links this act to His passing, noting that as soon as these two weeks of listening to the Ramayana were completed, the day of Vijayadashami arrived, and Baba attained the state of bodilessness. This final act of immersing Himself in a sacred scripture is a key event chronicled in Chapter 44.
