What is the main story told in Chapter 31, and what other stories are mentioned at the beginning?

Chapter 31 primarily narrates the story of a sannyasi from Madras named Vijayananda who is on a pilgrimage to Mansarovar. As detailed in the chapter, he hears of Sai Baba's fame and decides to stop in Shirdi for darshan. The beginning of Chapter 31 also briefly recaps several past stories, including those of the devotee of Saptashringi, Madhavrao's fulfilled vow, how Baba gave darshan in a dream for Khushalchet Ramlala, and the liberation of a cruel tiger. These brief mentions serve as a prelude to the main narrative about the sannyasi.
