What is the role of the Guru as described in the philosophy presented in Chapter 26?

According to the teachings in Chapter 26, the Guru is absolutely essential for spiritual awakening. The text states that in the world, "only the Guru is capable of granting the knowledge of Truth to a disciple." The author emphasizes that this visible, illusory world dissolves with true knowledge, which occurs when the time for awakening through the Guru's word arrives. The Guru's teachings, referred to as the Great Sayings (Mahavakyas), are the source of the "light of non-dual bliss." The chapter portrays the Guru as the one who can turn a disciple's intellect inward and lead them to self-realization.
