What is the primary story told in Chapter 5 of the Sai Satcharitra, and what is its main lesson?

Chapter 5 recounts a story involving a wise man named Devidas and an unnamed Fakir. Devidas, who was already established in Shirdi and considered a Guru by figures like Tatyaba, engaged in a scriptural debate with the Fakir. Devidas won the debate through his profound detachment, causing the Fakir to flee. Years later, the Fakir returned, his delusion dispelled, and bowed to Sainath. As explained in Chapter 5, the core lesson is about humility and the true nature of being a guru versus a disciple. Sai Baba himself exemplified this by maintaining the attitude 'His Guruship to him, and my discipleship to me,' teaching that true spiritual advancement requires one to act without pride and overcome the ego.
