Based on Chapter 16, what is the nature of the relationship between a Sadguru and a disciple, particularly regarding service and offerings?

Chapter 16 explains that a Sadguru is always 'Aptakama,' meaning one whose desires are already fulfilled, so he does not need anything from a disciple. Instead, the Sadguru fulfills the disciple's own desire to perform service, thereby helping the disciple become desireless. The text emphasizes the importance of intention. As stated in Chapter 16, if a simple leaf or flower is offered with genuine faith, the Guru accepts it with great love. However, if the same offering is made with pride, He will turn His face away. This demonstrates that sincere faith is valued far more than the material value of an offering or any outward ritual.
