According to Chapter 25, what is the significance of having one-pointed devotion towards a Sadguru like Sai Baba?

Chapter 25 places great emphasis on the power of one-pointed devotion. It states that Sai Baba, as the supreme embodiment of mercy, desires this singular focus from his followers. The chapter assures that a devotee who is faithful and filled with devotion will lack nothing in attaining their desires, as Sai wards off all their misfortunes and removes their suffering. To underscore this point, the text references Lord Krishna's words to Uddhava: "The Sadguru is indeed My own form." Therefore, as explained in Chapter 25, worshipping a Sadguru like Sai Baba with unwavering love and faith is the very definition of one-pointed devotion and the path to receiving divine grace and protection.
