How does Chapter 10 use the analogy of a boatman to describe the role of a Sadguru?

Chapter 10 of the Shri Sai Satcharitra uses a powerful analogy to explain the Sadguru's role in a devotee's life. It compares the journey across the worldly ocean of existence (Bhavasagar) to a physical sea voyage. Just as one trusts a boatman to safely cross an ocean, one must place complete trust in the great Guru to navigate the challenges of life and samsara. The chapter states that when the Sadguru becomes the boatman for a devotee, He guides them across the three types of miseries—physical, mental, and divine—leading them to liberation.
