How does the author describe the importance and role of the Guru in Chapter 26?

According to the excerpts from Chapter 26, the Guru is presented as the sole entity capable of granting a disciple the knowledge of Truth. The realization of the Self, which is self-luminous and eternal, is only possible when the Guru-Soul, who is God, is pleased. The author prays to Baba, the Sadguru, to turn his intellect inward and grant him the ability to discriminate between the eternal and the temporary. The chapter emphasizes having unshakeable faith in the Guru's words to overcome the false logic that otherwise keeps the mystery of the Self unsolved.
