In what ways is the Sadguru portrayed as an essential guide for both spiritual and worldly matters in Chapter 6?

Chapter 6 of the Sai Satcharitra portrays the Sadguru as an indispensable guide using powerful metaphors and descriptions. It begins by stating that whether for spiritual or worldly matters, a boat can only reach the far shore if the Sadguru is the helmsman, highlighting his crucial role in navigating life's challenges. The chapter also mentions that if a devotee's mind wanders into idle gossip, the Sadguru grants stability to their nonsensical speech. Furthermore, He actively participates in the devotee's spiritual learning, taking the form of Rama or Krishna during scriptural readings to make them hear His own life story, ensuring constant and personal guidance.
