What does Chapter 16 of Sai Satcharitra say about the nature of a Sadguru and their relationship with a disciple?

Chapter 16 describes the Sadguru as a "King of Kings" and the "Lord of the Empire of Self-Bliss," who has taken a physical body solely to uplift the poor and lowly. The text emphasizes that a Sadguru is always one whose desires are fulfilled, or 'Aptakama,' and their primary role is to fulfill the disciple's desire for service, ultimately making the disciple desireless. As explained in this chapter, the Guru accepts offerings made with faith and love but rejects those offered with pride. It is stated that there is no giver more generous than the Guru, as they provide the "Unthinkable Object" (Brahman), a far greater gift than what a wish-fulfilling gem could offer.
