Based on Chapter 16, what is the nature of a Sadguru like Sai Baba, and how does he regard the offerings and desires of his devotees?

According to Chapter 16, a Sadguru is 'Aptakama,' meaning one whose desires are already fulfilled, so he needs nothing from a disciple. However, he graciously fulfills the disciple's desire for service, thereby making the disciple desireless. The chapter emphasizes that the Sadguru accepts a simple leaf or flower offered with faith and love but will turn away from any offering made with pride. While he is an ocean of Truth, Consciousness, and Bliss and beyond outward rituals, he still enjoys them with satisfaction when they are performed with sincere faith.
