Based on Chapter 26, what is the role of a Sadguru and what should a disciple pray for?

According to the excerpts from Chapter 26, the Sadguru is presented as the only one capable of granting a disciple the true knowledge that dispels the illusion of the world. The chapter contains a direct prayer to Sai Baba, outlining what a devotee should seek. The narrator prays for the Guru to make their intellect turn inward, to be endowed with the ability to discriminate between the eternal and the temporary, and to be devoted to detachment. The prayer also asks for unshakeable faith in the Guru's words and for personal, experiential knowledge, as mere speech without experience is considered fruitless in spirituality.
