Can you explain the interaction between Devidas and the Fakir as described in Chapter 5?

According to Chapter 5, Devidas was a wise teacher who had settled in Shirdi twelve years before Baba's return. He was highly respected and considered a Guru by many. A Fakir arrived and engaged Devidas in a scriptural debate. With his profound detachment, Devidas defeated the Fakir, who then fled to Vaijapur in humiliation. The narrative in Chapter 5 explains that many years later, this same Fakir returned to Shirdi and bowed to Sainath, his delusion of being the Guru finally dispelled. Sai Baba, in his greatness, treated the repentant Fakir with respect, showcasing his profound humility.
