What specific religious text did Sai Baba listen to before his passing, as detailed in Chapter 43?

According to the account in Chapter 43, as Sai Baba's death drew near, he listened to the Ramayana for his own spiritual benefit. The text explicitly states that this was done "through the mouth of a Brahmin." This act is presented as a significant part of the events leading up to his final moments, demonstrating his profound religious awareness even as he was preparing to leave his physical body. This detail is highlighted in the chapter as part of the full explanation of the circumstances surrounding his departure, which also included the planning for his Samadhi.
