What are the ultimate benefits of surrendering completely to the Sadguru, as explained in Chapter 6?

Chapter 6 emphasizes the immense rewards of complete surrender to a Sadguru like Sai Baba. It begins by using the metaphor of a boat, stating that only the vessel with the Sadguru as its helmsman will successfully reach the far shore of existence. The chapter concludes by explicitly stating that by surrendering with body, speech, and mind to the capable Sai, a devotee can attain the four primary goals of human life—Dharma (righteous duty), Artha (material wealth), Kama (desire), and Moksha (liberation)—which come to hand naturally without even having to ask for them.
