What does Chapter 16 teach about the dynamic between a Sadguru and a disciple, particularly regarding service and offerings?

Chapter 16 explains that a Sadguru is 'Aptakama,' meaning one whose desires are already fulfilled, so he has no personal needs for a disciple to satisfy. The text clarifies that the Sadguru's true purpose in accepting service is to fulfill the disciple's own desire to serve, thereby helping the disciple become desireless. A key teaching in Chapter 16 is the importance of intention. The Guru is said to accept a simple leaf or flower offered with faith and love, but will turn away from the same offering if it is presented with pride. This shows that the Sadguru, being an ocean of Truth, Consciousness, and Bliss, values sincere faith far more than outward rituals or the material value of an offering.
