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

Chapter 26 of the Sai Satcharitra emphasizes that the Guru holds the supreme and indispensable role in a disciple's spiritual awakening. The text explicitly states that in the world, only the Guru is capable of granting the knowledge of Truth to a disciple. The Guru's words are likened to a moment of awakening that dissolves the dream-like, illusory world. When the Guru-Soul, who is God, is pleased, the true nature of the universe is realized. The devotee in Chapter 26 prays for unshakeable faith in the Guru's words, acknowledging that without the Guru's grace, the mystery of existence remains unsolved.
