According to Chapter 16, what is the nature of a Sadguru like Sai Baba, and how does he interact with his disciples' offerings?

Chapter 16 of the Sai Satcharitra describes the Sadguru as one whose desires are always fulfilled, making him "Aptakama." He accepts offerings, even a simple leaf or flower, with great love when given with sincere faith. However, this chapter explains that if an offering is made with pride, he will turn away from it. The Sadguru, being an ocean of Truth, Consciousness, and Bliss, does not care for outward rituals but enjoys them with deep satisfaction when they are performed with genuine faith. He also dons a "cloak of ignorance" to impart knowledge to the ignorant, always providing sweet instruction.
