What is the role of the Guru in attaining spiritual knowledge as described in Chapter 26?

Chapter 26 of the Sai Satcharitra emphasizes that the Guru is indispensable for spiritual realization. The text states that in the world, only the Guru is capable of granting the knowledge of Truth to a disciple. The author prays to Baba, the Sadguru, to make his intellect turn inward and to bestow the ability to discriminate between the eternal and the temporary. True awakening from the illusion of the world occurs through the Great Sayings (Mahavakyas) of the Sadguru. The author expresses a desire to place unshakeable faith in the Guru's words to solve the mystery of existence, highlighting that without the Guru, one remains lost in ignorance and false logic.
