According to Chapter 16, what is the dynamic between the Sadguru and a disciple regarding offerings and service?

Chapter 16 explains that a Sadguru is 'Aptakama,' meaning one whose desires are already fulfilled, so he does not need anything from a disciple. However, he graciously fulfills the disciple's own desire for service, which in turn helps the disciple become desireless. The text clarifies that the Guru accepts even a simple leaf or flower if offered with genuine faith and love, but will turn away from any offering made with pride. Although He is an ocean of Truth, Consciousness, and Bliss and is beyond outward rituals, Chapter 16 states that He still enjoys these rituals with deep satisfaction when they are performed with sincere faith, demonstrating the importance of the devotee's inner disposition.
