Based on the teachings in Chapter 26, what is the indispensable role of the Guru in a disciple's spiritual journey?

Chapter 26 of the Sai Satcharitra portrays the Guru as absolutely central to a disciple's spiritual awakening. The chapter establishes the world as an illusion of Maya and states that only the Guru is capable of granting the knowledge of Truth that dissolves this illusion. The text further clarifies that this realization only occurs when the "Guru-Soul, who is God, is pleased." The author prays for unshakeable faith in the Guru's words and for the Guru to grant personal, experiential knowledge, because without it, mere intellectual understanding is spiritually useless. Therefore, as presented in this chapter, the Guru is the sole source of true knowledge and the catalyst for transcending illusion.
