What powerful metaphors does Chapter 16 use to describe the Sadguru's role and power?

Chapter 16 employs several powerful metaphors to illustrate the Sadguru's nature. He is described as the 'umbrella-holder of the state of Self' and the 'staff-bearer of the consciousness of peace.' His speech is likened to the 'river of nectar from the ocean of Vedanta.' Most dramatically, the text mentions the 'sharp blade of the sword of Knowledge' that shines brilliantly in His hand. The very sight of this hand being raised to strike is said to make the 'tree of worldly existence' tremble in fear, symbolizing His power to destroy attachment to material life.
