How does Chapter 6 of the Sai Satcharitra describe the role and significance of a Sadguru like Sai Baba?

Chapter 6 of the Shri Sai Satcharitra emphasizes the supreme importance of a Sadguru, comparing him to a helmsman who can guide a boat across the ocean of worldly and spiritual matters. The text states that the mere mention of 'Sadguru' brings Sai Baba to mind, who then places his blessing hand upon the devotee's head. This divine touch, along with Udi from the Dhuni, is said to be wondrous, capable of burning away the ego and filling the heart with self-bliss. The chapter posits that with a Sadguru as the guide, one is assured of reaching the 'far shore' of life's journey.
