Can you explain the boatman analogy used in Chapter 10 to describe the Sadguru's role?

Chapter 10 employs a powerful analogy to illustrate the Sadguru's essential role in a devotee's life. It compares the journey through worldly existence (Bhavasagar) to crossing a vast ocean. Just as a person trusts a boatman to safely navigate a physical ocean, a spiritual seeker must place their trust in the Guru to cross the treacherous ocean of worldly life. The chapter states that when the Sadguru becomes the 'boatman,' devoted bhaktas can successfully cross over the three types of miseries—physical, mental, and divine. This analogy beautifully conveys the idea that navigating life's struggles and attaining liberation requires the guidance and grace of a capable Guru.
