What is the main spiritual lesson conveyed through the story of the Fakir and Devidas in Chapter 5?

The primary lesson from the story in Chapter 5 revolves around humility and the importance of a Guru-disciple relationship. After a Fakir was defeated in a debate by the wise Devidas, he fled, only to return years later and bow to Sainath. His delusion of being a Guru was dispelled. Sai Baba's profound play, as mentioned in the text, was to maintain the feeling that "he is the Guru and I am the disciple." This chapter teaches that one must either become someone's disciple or make someone their Guru to cross the ocean of worldly existence. The text emphasizes that one who makes a firm resolution to act without pride can "climb the fort of selflessness."
