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

The relationship between a Guru and disciple is a central theme in Chapter 48 of the Shri Sai Satcharitra. The text describes an ideal Sadguru as one who is entirely selfless, never even dreaming of receiving service from a disciple. In fact, this chapter states that a true Sadguru wishes to sacrifice his own body for the sake of the disciple. This selflessness is coupled with a complete lack of egoism; a Sadguru does not see the disciple as insignificant but rather views them as the Supreme Brahman, showing them a fatherly love and never desiring their own livelihood from them.
