Could you provide a comprehensive overview of the stories and themes introduced in Chapter 31?

Chapter 31 begins by briefly recapping past stories, such as those of the Saptashringi devotee, Madhavrao, and Megha, before setting the stage for a new, wonderful story. It delves into the philosophy of one's state of mind at death and the importance of remembrance of the Name. The main narrative then introduces a sannyasi, Vijayananda of Madras, who is journeying to Mansarovar. As described in Chapter 31, he stops in Shirdi to see Sai Baba, but becomes disheartened after learning of the journey's difficulties from Swami Somdevji. His first encounter with Baba is confusing, as Baba asks for him to be sent away, setting up the central drama of the chapter.
