Can you explain the state of Self-Bliss and the power of knowledge as depicted in Chapter 16?

Chapter 16, titled 'The Quest for Brahma-jnana,' portrays the Guru-King as the 'Idol seated on the throne of peace' within an 'Empire of Self-Bliss.' This state is characterized by natural non-duality, where the six enemies like lust and anger cannot survive. The power of knowledge is described metaphorically as a 'sharp blade of the sword of Knowledge.' This sword is so potent that the mere sight of his hand raised to strike with it causes the 'tree of worldly existence' to tremble in fear, illustrating knowledge's ability to destroy worldly attachment.
