Can you recount the story of Devidas and the Fakir as told in Chapter 5 of the Sai Satcharitra?

Certainly. According to Chapter 5 of the Sai Satcharitra, a wise man named Devidas had settled in Shirdi twelve years before Baba's arrival with the wedding party. He was considered a Guru by many, including Tatyaba. When the Fakir (Sai Baba) was brought before him, they held a scriptural debate. Devidas, with his wisdom and detachment, defeated the Fakir, who then left for Vaijapur. Many years later, the Fakir returned, his delusion of being the Guru dispelled, and bowed to Sainath. Baba, in turn, treated him with respect, showcasing a profound lesson in humility.
