What specific spiritual practice did Sai Baba undertake in the two weeks immediately before his passing, and on what significant day did he attain Mahasamadhi?

According to Chapter 44 of the Sai Satcharitra, Sai Baba, knowing his end was near, engaged in a focused spiritual practice for fourteen days and nights. During this period, he listened to the Ramayana being recited by a Brahmin. This intense contemplation concluded at the end of the two weeks, and as described in the chapter, Baba attained the state of bodilessness, or passed away, on the auspicious day of Vijayadashami. This marked the culmination of his earthly journey after this dedicated period of listening to the sacred epic.
