What is the role of the Guru in achieving spiritual awakening, as detailed in this chapter?

According to the teachings in Chapter 26, the Guru is indispensable for spiritual awakening. The text states that in the world, only the Guru is capable of granting the knowledge of Truth to a disciple. It is through the "Great Sayings (Mahavakyas) of the Sadguru" that the "light of non-dual bliss shines forth." The chapter contains a prayer asking the Guru to make the devotee's intellect turn inward and to bestow the ability to discriminate between the eternal and the temporary. This highlights that the Guru is the key to dispelling the illusion of Maya and realizing the true nature of the Self, as mentioned in Chapter 26.
