Can you summarize the primary narrative presented in Chapter 5 of the Sai Satcharitra regarding the Guru and disciple?

Chapter 5 narrates a profound story about a man who once deluded himself into thinking he was Sai Baba's Guru. After fleeing and living in Vaijapur for many years, he eventually returned and bowed to Sainath, his delusion dispelled. As detailed in Chapter 5, Sai Baba treated this man with the same respect as before, embodying the lesson of humility and discipleship. This interaction serves as a powerful illustration of the principle, 'His Guruship to him, and my discipleship to me,' emphasizing that making oneself a disciple is the surest way to spiritual progress.
