Describe the events that led to a Fakir leaving Shirdi and his eventual return, as detailed in Chapter 5.

As detailed in Chapter 5, a Fakir was brought before Devidas, a wise man residing in Shirdi, for a scriptural debate. Devidas, with his profound detachment and wisdom, defeated the Fakir in this debate. Humiliated, the Fakir fled from Shirdi and went to live in Vaijapur. For many years, he harbored the delusion that he was the Guru. However, after a long period, he had a change of heart and returned to Shirdi. Upon his return, he was no longer deluded; he became pure through repentance and bowed to Sainath. Baba, in his infinite grace, treated him with the same respect as before, concluding this "profound play" of Guru and disciple.
