What is the primary story introduced in Chapter 31 about a sannyasi?

Chapter 31 introduces the compelling story of a sannyasi from Madras named Vijayananda. As the verses explain, this sannyasi was on a determined pilgrimage from Madras to Mansarovar. However, upon hearing of Sai Baba's great fame and renown along the way, he felt a strong longing for darshan. This desire compelled him to alter his journey and stop in the village of Shirdi to seek out the great saint, illustrating how Baba draws devotees to His feet from far-flung places.
