What is the main story about the Guru and disciple relationship detailed in Chapter 5?

Chapter 5 of the Sai Satcharitra recounts a profound lesson on the Guru-disciple relationship through a specific narrative. It tells of Devidas, a wise teacher in Shirdi whom even Tatyaba took as his Guru. A Fakir, who considered himself a Guru to Sai, was brought before Devidas for a scriptural debate. As described in Chapter 5, Devidas defeated the Fakir with his detachment, and the Fakir fled, only to return years later to bow to Sainath, his delusion dispelled. This story, which Mahalsapati originally related, highlights Sai Baba's own practice of humility, as He maintained the feeling that "he is the Guru and I am the disciple," teaching a powerful lesson on selflessness.
