Describe the ideal relationship between a Sadguru and their disciple as outlined in Chapter 48.

According to the teachings in Chapter 48, the relationship between a Sadguru and a disciple is marked by the Guru's complete selflessness and love. A true Sadguru is a benefactor who is free from the ego of thinking they are great and the disciple is insignificant. This chapter states that a Sadguru considers the disciple as the Supreme Brahman and has a fatherly love for them. Crucially, a Sadguru never even dreams of receiving service from a disciple; rather, they are willing to sacrifice their own body for the disciple's benefit and do not desire their own livelihood from them.
