Why is the Guru considered so essential according to the philosophy in Chapter 26?

According to the teachings in Chapter 26, the Guru is fundamentally important because only the Guru is capable of granting the disciple true knowledge. The text explains that the visible world is illusory, a product of Maya, and this illusion only dissolves when the time for awakening through the Guru's word arrives. The author prays to Baba, the Sadguru, to provide this knowledge through experience, as without the Guru's grace, the mystery of our true nature remains unsolved. The Guru is seen as the one who can make the intellect turn inward and reveal the light of non-dual bliss.
