What are the 'eight ministers' mentioned in Chapter 16, and what do they represent in the spiritual journey?

In the allegorical court of the Guru-King described in Chapter 16, there are eight ministers engaged in His service. These are listed as Detachment, Devotion, Pure Knowledge, Hearing (Shravan), Reflection (Manan), Meditation (Nididhyasan), Self-investigation, and Realization. This imagery suggests that these eight qualities and practices are the essential components of the spiritual path. They are the chief functionaries that serve the ultimate goal of attaining the state of Self-bliss and Pure Consciousness, which the Guru embodies.
