I'm trying to understand the role of a Guru. What does this section of Chapter 26 say about the importance of having one?

According to the excerpts from Chapter 26, the Guru holds the ultimate importance in a disciple's spiritual journey. The text explicitly states that in the world, "only the Guru is capable of granting the knowledge of Truth to a disciple." The author demonstrates this by praying to Sai Baba to make his intellect turn inward and to bestow upon him the ability to discriminate between the eternal and the temporary. The chapter emphasizes that awakening from the illusion of the world happens through the Guru's word, and that unshakeable faith in the words of the Guru and Vedanta is essential for spiritual progress.
