What does Chapter 48 reveal about the ideal relationship between a Sadguru and a disciple, particularly regarding ego and expectations of service?

Chapter 48 provides a profound description of the selfless nature of the Sadguru-disciple relationship. A true Sadguru, according to the text, is entirely free from the ego of thinking the Guru is great while the disciple is insignificant. On the contrary, a Sadguru considers the disciple as the Supreme Brahman and shows fatherly love. A key point highlighted in Chapter 48 is that a Sadguru never even dreams of receiving service from a disciple, nor do they desire their own livelihood from them. Instead, the Sadguru is one who wishes to sacrifice their own body for the sake of the disciple, making them a true benefactor.
