What does Chapter 25 reveal about the importance of devotion and the nature of a Sadguru?

Chapter 25 emphasizes that Sai Baba desires "one-pointed devotion" from his followers, stating that a faithful and devoted person will not lack anything in attaining their desires. The chapter draws a powerful parallel by quoting Krishna's words to Uddhava: "The Sadguru is indeed My own form." This highlights the divine nature of the Sadguru. Therefore, the text advises that one should worship the Sadguru with love, which is the essence of one-pointed devotion. It promises that once this faith is established, Sai will ward off misfortunes and remove the suffering of that devotee.
