How does Sai Baba, as the Sadguru, interact with his devotees' offerings, and what is his true nature according to Chapter 16?

The Sadguru is described as 'Aptakama,' meaning his desires are already fulfilled, so he has no need for material offerings. As explained in Chapter 16 of the Sai Satcharitra, he accepts even a simple leaf or flower offered with genuine faith and love but will turn away from any offering made with pride. He is an ocean of Truth, Consciousness, and Bliss, and he values the sincere faith behind an act more than the outward ritual itself. This chapter emphasizes that the Guru's generosity is unparalleled, as he is the ultimate refuge who gives his devotees the 'Unthinkable Object,' which is Brahman itself.
