Based on Chapter 5, what was the philosophical lesson demonstrated by Sai Baba through the interaction with the Fakir who had debated Devidas?

The underlying lesson in Chapter 5 revolves around humility, selflessness, and the nature of Guruship. After the Fakir who debated Devidas returned humbled, Baba treated him with respect, maintaining the feeling that 'he is the Guru and I am the disciple.' The chapter explains this was a profound lesson that Sainath himself practiced, teaching that one must burn the pride of the body to achieve the supreme goal. The text emphasizes that one who makes a firm resolution in his mind will climb the 'fort of selflessness,' highlighting the importance of acting without pride to attain spiritual welfare.
