What are the main stories and philosophical points introduced in Chapter 31?

Chapter 31 of the Shri Sai Satcharitra begins by briefly recapping several past stories, including those of a Saptashringi devotee, Madhavrao, Khushalchet, Mankar, and Megha. It then transitions into a philosophical discussion on the importance of one's state of mind at the time of death, emphasizing that practicing the remembrance of God's name is crucial for liberation. As Chapter 31 explains, this practice ensures one does not get confused in their final moments. The main narrative introduced is that of a sannyasi from Madras named Vijayananda, who is on a pilgrimage to Mansarovar but stops in Shirdi upon hearing of Sai Baba's fame, setting the stage for a profound encounter.
