Who was Devidas and what was his role in the events described in Chapter 5?

As detailed in Chapter 5 of the Sai Satcharitra, Devidas was a wise individual who had settled in Shirdi twelve years before Sai Baba's return with the wedding party. He was a respected teacher who taught lessons regularly, even instructing Appa Bhill on a slate and making people recite the Venkatesh Stotra. His wisdom was such that prominent individuals like Tatyaba took him as their Guru, and other leading disciples revered him. His significant role in the chapter's narrative involves a scriptural debate with a Fakir. Devidas, with his superior wisdom and detachment, defeated the Fakir, causing the Fakir to flee Shirdi, which set the stage for a lesson on pride and humility.
