What is the main story about a Guru and disciple in Chapter 5 of Sai Satcharitra?

Chapter 5 of the Sai Satcharitra recounts a significant story involving a Guru-disciple dynamic. It tells of Devidas, a wise ascetic who lived in Shirdi before Baba's arrival, and a Fakir who challenged him to a scriptural debate. Devidas defeated the Fakir with his detachment, causing the Fakir to flee. As the chapter explains, many years later, this same Fakir returned and bowed to Sainath, his delusion of being a Guru having been dispelled. Baba, in his profound play, treated the man with respect, demonstrating the lesson of humility and the importance of recognizing a true master. This entire incident, as told by Mahalsapati, serves as a lesson on guruship and repentance.
