What philosophical lesson regarding guruship and humility does Chapter 5 teach through the story of Devidas and the Fakir?

Chapter 5 imparts a profound lesson on humility and the true nature of being a Guru versus a disciple. After the Fakir (Sai) returns from Vaijapur, his delusion of being a Guru is dispelled. Despite this, Baba continues to treat Devidas with respect. The text highlights Sai's principle: "His Guruship to him, and my discipleship to me." This illustrates that true spiritual advancement comes from acting without pride and being willing to become anyone's disciple to achieve the supreme goal. Chapter 5 emphasizes that one who has burned the pride of the body can climb the 'fort of selflessness' and resides in a state of non-duality.
