What does Chapter 48 say about the relationship between a Sadguru and their disciple, specifically concerning ego and service?

Chapter 48 provides a detailed description of the ideal Sadguru-disciple relationship, emphasizing humility and selflessness. A true Sadguru, it says, is entirely free from the egoism of thinking "The disciple is an insignificant thing and the Guru is the greatest of the great." Instead, they view the disciple as the Supreme Brahman and have a fatherly love for them. Furthermore, the chapter explicitly states that a Sadguru never desires their own livelihood from the disciple and never even dreams of receiving service. In fact, a Sadguru is one who wishes to sacrifice their own body for the sake of the disciple, making them a true benefactor.
