What lesson about the Guru-disciple relationship is highlighted in Chapter 5?

Chapter 5 emphasizes a profound lesson on humility and the Guru-disciple dynamic through Sai Baba's own actions. Even after a Fakir, who once challenged Devidas, returned and bowed to Sainath, Baba continued to treat Devidas with respect. The text states, "His Guruship to him, and my discipleship to me." This was a lesson Sainath himself practiced. Chapter 5 teaches that to achieve spiritual progress, one must act without pride, burn the pride of the body, and be willing to become a disciple to achieve the supreme goal. This selfless determination is described as the way to "climb the fort of selflessness."
