Can you list the spiritual concepts that are personified as the Sadguru's royal court in Chapter 16?

Certainly. In Chapter 16, the Sadguru's spiritual majesty is described through the allegory of a royal court. The bards who sing his glory are the four Vedas, six Shastras, and eighteen Puranas. The text identifies his eight ministers, who are constantly engaged in his service, as Detachment, Devotion, Pure Knowledge, Hearing (Shravan), Reflection (Manan), Meditation (Nididhyasan), Self-investigation, and Realization. Furthermore, the divine gems that shine as ornaments around his neck are identified as Peace and Self-control, completing this profound symbolic image.
