Chapter 16 mentions 'eight ministers' serving the Guru-King. What are they and what does this signify?

In the allegorical depiction of Sai Baba as a "Guru-King," Chapter 16 of the Sai Satcharitra lists eight qualities and practices as the ministers engaged in His service. These "eight ministers" are identified as Detachment, Devotion, Pure Knowledge, Hearing (Shravan), Reflection (Manan), Meditation (Nididhyasan), Self-investigation, and Realization. This personification signifies that these profound spiritual qualities and disciplines are the essential components that constitute and support the enlightened state that the Guru embodies. As Chapter 16 illustrates, attaining this state of Self-bliss involves the harmonious function of this entire cabinet of spiritual practices.
