How important is a Guru for spiritual progress according to the teachings in Chapter 26?

According to Chapter 26, the Guru is absolutely essential for attaining spiritual knowledge and liberation. The text explicitly states that in the world, only the Guru is capable of granting the knowledge of Truth to a disciple. The author prays to Baba to make their intellect turn inward and grant discrimination between the eternal and the temporary. This chapter emphasizes that the illusion of the world dissolves only when the time for awakening through the Guru’s word arrives. The Guru's teachings, or Mahavakyas, are what bring forth the light of non-dual bliss, making the Guru's role indispensable for a seeker.
