Can you summarize the key themes and metaphors presented in Chapter 16 of the Sai Satcharitra?

Chapter 16 of the Sai Satcharitra uses rich metaphors to describe the Sadguru, likening him to a magnificent king. The chapter explains that his court includes the four Vedas, six Shastras, and eighteen Puranas as bards, with a canopy of Pure Consciousness overhead. His ministers are qualities like Detachment, Devotion, and Self-investigation. The chapter emphasizes the importance of faith and humble service to the Guru, stating that He accepts offerings made with love but rejects those offered with pride. It's also mentioned that the Guru is a generous giver, bestowing the "Unthinkable Object" (Brahman) upon his devotees, which is far greater than what a wish-fulfilling gem could provide. The text highlights that the Sadguru is always one whose desires are fulfilled (Aptakama) and he helps his disciples become desireless.
