How does Chapter 6 use the analogy of a helmsman to explain the role of a Sadguru in a person's life?

Chapter 6 begins by establishing the vital role of a Sadguru with a powerful analogy. It states that whether dealing with spiritual or worldly matters, a person's life is like a boat, and only the boat with a Sadguru as its helmsman will successfully reach the far shore. This metaphor illustrates that the Sadguru provides indispensable guidance and protection, steering the devotee safely through life's challenges. The chapter reinforces this by stating that complete surrender to a capable Sadguru like Sai allows a devotee to naturally achieve the four main goals of human life: Dharma, Artha, Kama, and Moksha.
