How does Chapter 16 explain Sai Baba's perspective on offerings and service from his disciples?

According to the teachings in Chapter 16, the Sadguru's desires are always fulfilled, so a disciple cannot truly fulfill any need for Him. Instead, the Sadguru fulfills the disciple's own desire to serve, thereby making the disciple desireless. The text emphasizes that He accepts even a simple leaf or flower offered with genuine faith and love, but will immediately turn away from any offering made with pride. Though He is an ocean of Truth, Consciousness, and Bliss beyond outward rituals, He still enjoys and is satisfied by rituals performed with sincere faith.
