How does Chapter 48 describe the ideal relationship between a Sadguru and their disciple, particularly concerning service, ego, and love?

Chapter 48 provides a profound description of the selfless and egoless relationship a Sadguru has with their disciple. A true Sadguru is defined as one who never dreams of receiving service from a disciple but instead is willing to sacrifice their own body for the disciple's sake. Furthermore, a Sadguru is completely free from the egoism of seeing themselves as superior; they view the disciple as a form of the Supreme Brahman and hold a "fatherly love" for them. As detailed in Chapter 48, they do not desire their own livelihood from the disciple and treat everyone, great or small, with equality. This selfless, loving, and non-hierarchical attitude is presented as the hallmark of the most superior Sadguru.
