How does Chapter 16 describe Sai Baba's power to help people overcome worldly attachments and illusions?

Chapter 16 uses strong metaphors to illustrate the Sadguru's role in liberating devotees from worldly struggles. It states that in his presence, the "six enemies" like lust and anger cannot survive for even a second. Furthermore, it describes a "sharp blade of the sword of Knowledge" that shines brilliantly. The mere sight of his hand raised to strike with this sword causes the "tree of worldly existence (Bhav-vriksha)" to tremble in fear. This imagery powerfully conveys how the Guru's wisdom and grace can sever the roots of illusion and attachment, helping to uplift the poor and lowly for whom he has taken a body, as mentioned in this chapter.
