How is the role and importance of a Guru described in Chapter 26?

Chapter 26 emphasizes that in this world, only the Guru is capable of granting the disciple the knowledge of Truth. The author illustrates this by praying to Sai Baba, asking Him to make his intellect turn inward and grant the ability to discriminate between the eternal and the temporary. The text highlights that without the Guru's grace and the light of His teachings (Mahavakyas), one remains trapped in ignorance, mistaking illusion for reality. The author expresses a desire for unshakeable faith in the Guru's words, recognizing that the Guru is the one who can make spiritual knowledge meaningful through direct experience.
