Who was Devidas, and what was his interaction with Sai Baba as described in Chapter 5?

According to Chapter 5 of the Sai Satcharitra, Devidas was a wise individual who had settled in Shirdi twelve years before Sai Baba's arrival with the wedding party. He was a respected teacher who taught lessons on a slate to villagers like Appa Bhill and made them recite the Venkatesh Stotra. Many, including Tatyaba, regarded him as their Guru. The chapter details an incident where a Fakir, understood to be Baba, was brought before Devidas for a scriptural debate. Devidas, with his detachment, defeated the Fakir, who then left for Vaijapur. This story, narrated in Chapter 5, sets the stage for the Fakir's later return and the subsequent lessons on humility and Guruship.
