Chapter 16 mentions eight 'ministers' serving the Guru-King. What are these ministers and what do they represent on the spiritual path?

In the allegorical court of the Sadguru described in Chapter 16, there are eight 'ministers' constantly engaged in His service. These ministers are not people, but rather key spiritual principles and practices. As listed in Chapter 16, they are: Detachment (Vairagya), Devotion (Bhakti), Pure Knowledge (Shuddha Jnana), Hearing (Shravan), Reflection (Manan), Meditation (Nididhyasan), Self-investigation (Atma-chintan), and Realization (Sakshatkar). These represent the complete eight-fold path of spiritual discipline that, when followed, constitutes service to the Guru and leads to the state of Self-bliss he embodies.
