Can you summarize the story told in Chapter 5 about Devidas, the Fakir, and Sai Baba's lesson on Guruship?

Chapter 5 narrates the story of Devidas, a wise teacher who had settled in Shirdi twelve years before Baba's return with the wedding party. Devidas was considered a Guru by many, including Tatyaba. A Fakir once challenged Devidas to a scriptural debate but was defeated by Devidas's detachment and fled. As described in Chapter 5, this same Fakir later returned after many years and bowed to Sainath, his delusion of being a Guru to Sai having been dispelled. Baba, in his profound play, treated the Fakir with respect, demonstrating the lesson of humility by maintaining the feeling that "he is the Guru and I am the disciple." This chapter highlights the importance of accepting a Guru to achieve spiritual progress.
