How does Chapter 26 illustrate the indispensable role of the Guru in achieving spiritual realization?

According to the teachings in Chapter 26, the Guru is the sole entity capable of granting a disciple the knowledge of Truth. The text emphasizes that the illusion of the world dissolves only when the time for awakening through the Guru's word arrives. The author makes a direct appeal to Sai Baba, the Sadguru, to turn their intellect inward and instill discrimination between the eternal and the temporary. The chapter posits that when the Guru-Soul, who is God, is pleased, one can realize the self-luminous and eternal nature of the Self, underscoring that the Guru is the ultimate guide to overcoming Maya.
