Can you provide a summary of the main events and teachings discussed in Chapter 5 of the Sai Satcharitra?

Chapter 5 recounts the story of Devidas, a wise man who had settled in Shirdi twelve years prior to Baba's arrival with the wedding party. Devidas served as a teacher and was regarded as a Guru by figures like Tatyaba. The chapter describes a scriptural debate where Devidas, through his detachment, defeated a Fakir. A central theme, as explained in Chapter 5, is Sai Baba's profound humility. He consistently maintained the feeling that Devidas was the Guru and he was the disciple, teaching the lesson, "His Guruship to him, and my discipleship to me." This narrative, conveyed by Mahalsapati, underscores the importance of shedding pride to achieve spiritual welfare and concludes by previewing future topics like the mosque's history and Baba's lineage.
