Based on Chapter 26, what is the role of a Guru in helping a disciple overcome ignorance?

According to the teachings in Chapter 26 of the Sai Satcharitra, the Guru is paramount and indispensable for spiritual awakening. The text states that in the entire world, only the Guru is capable of granting the knowledge of Truth to a disciple. The author prays to Sai Baba to turn his intellect inward and grant him the ability to discriminate between the eternal and the temporary. The chapter emphasizes that ignorance, which causes one to mistake a rope for a snake, can only be dispelled when the time for awakening through the Guru's word arrives, leading to the dissolution of the illusory world.
