Chapter 16 mentions 'eight ministers' engaged in the Guru's service. What are they, and what does this symbolism represent?

In the metaphorical court of the Guru-King described in Chapter 16, eight 'ministers' are listed as being constantly engaged in His service. These are not people, but spiritual principles and practices: Detachment, Devotion, Pure Knowledge, Hearing (Shravan), Reflection (Manan), Meditation (Nididhyasan), Self-investigation, and Realization. This symbolism illustrates that the path to the supreme state, embodied by the Sadguru, is administered and supported by these essential components of spiritual discipline. They are the active forces and qualities that a seeker must engage with to serve and ultimately realize the Self, which is the Guru's true nature.
