What is the role of the Guru in achieving spiritual awakening, according to the teachings in Chapter 26?

According to Chapter 26, the Guru is absolutely essential for spiritual awakening, as the text states that "only the Guru is capable of granting the knowledge of Truth to a disciple." The illusion of the world dissolves when the time for awakening arrives through the Guru's word. The chapter emphasizes that through the "Great Sayings (Mahavakyas) of the Sadguru," the light of non-dual bliss shines forth. The author prays for unshakeable faith in the Guru's words, acknowledging that without the Guru, the mystery of existence remains unsolved because the intellect is often mounted on false logic.
