According to Chapter 26, what is the role of the Guru in a disciple's spiritual journey?

Chapter 26 emphasizes that the Guru is indispensable for spiritual awakening. It states unequivocally that in the world, only the Guru is capable of granting the knowledge of Truth to a disciple. The Guru's teachings, or "Great Sayings," are the catalyst through which the illusion of Maya dissolves and the light of non-dual bliss shines forth. The chapter includes a prayer to the Sadguru, Sai Baba, asking Him to make the intellect turn inward and to bestow the discrimination between the eternal and the temporary. Realization of the truth, as mentioned in this chapter, only occurs when the "Guru-Soul, who is God, is pleased."
