According to Chapter 6, what is the role of a Sadguru and how does Sai Baba embody this role?

Chapter 6 of the Sai Satcharitra explains that a Sadguru acts as a helmsman, capable of guiding a person's boat—representing their life—to the far shore, whether in spiritual or worldly matters. The chapter poignantly notes that the moment the word 'Sadguru' is uttered, Sai Baba is the first to be remembered. He is described as standing right in front of the devotee, placing his blessing hand on their head. This act is said to bring self-bliss and love. The text emphasizes that when Sai is the helmsman, the journey is assured of a successful conclusion, highlighting his supreme role as a spiritual guide.
