Chapter 5 mentions a lesson, "His Guruship to him, and my discipleship to me." Can you explain the context of this teaching?

This powerful lesson is presented in Chapter 5 in the context of the story involving Devidas and a certain Fakir. After the Fakir was defeated in a debate by Devidas and left Shirdi, he returned many years later. Upon his return, his previous delusion that he was a Guru to Sai Baba was gone, and he bowed to Sainath in repentance. Despite this, Baba continued to treat him with respect, maintaining the feeling that "he is the Guru and I am the disciple." Chapter 5 explains that Sainath himself practiced this lesson, "His Guruship to him, and my discipleship to me," demonstrating the profound humility and selflessness required to cross the ocean of existence. This behavior shows that one must either become a disciple or accept someone as their own to achieve the supreme goal.
