What is the role of a Guru in spiritual awakening, as described in Chapter 26?

Chapter 26 of the Sai Satcharitra emphasizes that the Guru is indispensable for spiritual awakening. The text states that in the world, only the Guru is capable of granting the knowledge of Truth to a disciple. The author articulates a deep prayer to Sai Baba, asking Him to make their intellect turn inward and bestow the ability to discriminate between the eternal and the temporary. This is because, as the chapter explains, the devotee's intellect is often mounted on false logic, and the mystery of reality can only be solved by placing unshakeable faith in the words of the Guru and Vedanta.
