Can you detail the roles of Devidas and the Fakir as described in Chapter 5?

According to Chapter 5, Devidas was a very wise individual who arrived in Shirdi long before Baba's main appearance. He acted as a teacher to locals like Appa Bhill and was regarded as a Guru by Tatyaba and others. A Fakir challenged Devidas to a scriptural debate, but Devidas's wisdom and detachment led to the Fakir's defeat. The Fakir then fled to Vaijapur. Chapter 5 further narrates that this same Fakir returned years later, his delusion of being a Guru to Sai now gone, and he bowed to Sainath in repentance. Baba, in turn, treated him with respect, demonstrating profound humility.
