How does Chapter 16 describe the power of Knowledge as personified by the Guru?

Chapter 16 of the Sai Satcharitra powerfully illustrates the transformative power of Knowledge as embodied by the Guru. It is personified as a "sharp blade of the sword of Knowledge" that "shines brilliantly." The impact of this spiritual wisdom is so immense that the mere sight of the Guru's hand raised to strike with this sword causes the "tree of worldly existence (Bhav-vriksha)" to tremble in fear. This striking metaphor, found in Chapter 16, signifies that the Guru's knowledge has the absolute power to sever the roots of worldly attachment and illusion, which bind a soul to the cycle of birth and death.
