What is Sai Baba's perspective on offerings and rituals from his devotees, as detailed in Chapter 16?

According to Chapter 16, the Sadguru is always 'Aptakama,' meaning one whose desires are already fulfilled, and he has no need for material things. However, he graciously accepts any offering, even a simple leaf or flower, when it is given with sincere faith and love. Conversely, if an offering is made with pride, he will turn away from it. The chapter clarifies that while he is an ocean of Truth, Consciousness, and Bliss and beyond outward rituals, he still enjoys them with deep satisfaction when they are performed with genuine devotion, thereby fulfilling the devotee's desire to serve.
