What is the role of the Guru in achieving spiritual awakening, as described in Chapter 26?

According to Chapter 26, the Guru is indispensable for 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, or 'Mahavakyas', are the catalyst for achieving the light of non-dual bliss, which dispels the illusion of the material world. The devotee prays for the Guru to make their intellect turn inward and grant the ability to discriminate between the eternal and the temporary. Chapter 26 highlights that when the Guru-Soul, who is God, is pleased, one realizes the true nature of existence. Therefore, unshakeable faith in the Guru's words is presented as essential for self-knowledge to manifest.
