Can you explain the metaphor of the Sadguru as a 'boatman' as described in the tenth chapter?

In Chapter 10, the metaphor of the Sadguru as a 'boatman' is used to explain the importance of trust in the spiritual journey. The text draws a parallel: just as one trusts a boatman to safely cross a physical ocean, a devotee must place their trust in the great Guru to cross the 'ocean of existence,' also known as Bhavasagar. The chapter elaborates that when the Sadguru becomes the boatman for his devoted bhaktas, they are able to successfully cross over the three types of miseries: physical, mental, and divine. This illustrates the Guru's role as a guide and protector.
