How does Chapter 6 explain the Sadguru's role in guiding a devotee's spiritual journey and understanding of scriptures?

According to Chapter 6, the Sadguru is the essential helmsman for a devotee's life, ensuring their "boat" reaches the far shore in both spiritual and worldly matters. When a devotee reads scriptures or Puranas, the Sadguru's presence is felt at every step. The text elaborates that Sai Baba Himself can take the form of Rama or Krishna, making the devotee hear His own life story through the ancient texts. For instance, when one listens to the Bhagavat, it can feel as if Sai has appeared as Krishna and is singing the Uddhava Gita for the devotee's personal welfare, thus making scripture a living, personal experience.
