Can you provide a summary of the key narratives and philosophical teachings presented in Chapter 31 of the Shri Sai Satcharitra?

Chapter 31 begins by recapping several past stories, including those of a devotee of Saptashringi, Madhavrao, and a tiger given a place at Sai's feet. The chapter then introduces its main story about a sannyasi from Madras named Vijayananda, who is on a pilgrimage to Mansarovar and stops in Shirdi. As detailed in the chapter, there is also a significant philosophical discussion on the importance of one's state of mind at the time of death. The text emphasizes that whatever one meditates upon at death is the form one attains, highlighting the value of remembering God's name and seeking the guidance of saints.
