The text mentions 'eight ministers' in the service of the Guru-King. What are these ministers, and what does this symbolism represent?

In the allegorical court of the Guru-King described in Chapter 16, the eight ministers are listed as Detachment, Devotion, Pure Knowledge, Hearing (Shravan), Reflection (Manan), Meditation (Nididhyasan), Self-investigation, and Realization. This symbolism represents the essential qualities and advanced spiritual practices that constitute and support the supreme state of the Sadguru. They are not literal people but are the very pillars of the 'Empire of Self-Bliss,' signifying the path and the components necessary for achieving ultimate spiritual realization under the Guru's guidance.
