Describe the ideal relationship between a Sadguru and their disciple, focusing on the Sadguru's selflessness, as detailed in Chapter 48.

Chapter 48 provides a profound description of a Sadguru's selfless nature and their ideal relationship with a disciple. A true Sadguru is characterized by a complete lack of egoism and never considers the disciple to be insignificant. In fact, the chapter states that a Sadguru "never even dreams of receiving service from a disciple, but instead wishes to sacrifice his own body for the sake of the disciple." This passage highlights that a Sadguru sees the disciple as the Supreme Brahman, holds a "fatherly love" for them, and does not seek their own livelihood from the relationship. This selfless love and humility are presented as the hallmarks of the most superior Sadguru.
