Can you explain the significance of the Sadguru's 'sword of Knowledge' and the 'tree of worldly existence' as mentioned in Chapter 16?

In the poetic descriptions at the start of Chapter 16, the Sadguru is depicted with a "sharp blade of the sword of Knowledge" that shines brilliantly. This sword is a metaphor for the divine wisdom and discriminating insight that the Guru wields. The text states that upon seeing His hand raised to strike with this sword, the "tree of worldly existence (Bhav-vriksha) trembles in fear." The 'tree of worldly existence' represents the cycle of birth, death, and suffering (samsara) rooted in illusion and attachment. Therefore, as Chapter 16 illustrates, the Guru's teachings and grace, symbolized by the sword of Knowledge, have the power to cut through a devotee's ignorance and attachments, thereby liberating them from worldly bondage.
