What are some of the key poetic metaphors used in Chapter 16 to illustrate the Sadguru's divine attributes and power?

The text of Chapter 16 is rich with poetic metaphors to describe the Sadguru. His sweet speech is likened to a "river of nectar from the ocean of Vedanta." His power is symbolized by the "sharp blade of the sword of Knowledge," which is so brilliant that the mere sight of his hand raised to strike causes the "tree of worldly existence" to tremble in fear. Furthermore, the chapter describes Peace and Self-control as "divine gems shining as ornaments around His neck," beautifully illustrating the internal qualities that adorn the perfect master.
