How does Chapter 6 describe the role of the Sadguru in guiding a devotee towards spiritual and worldly success?

The beginning of Chapter 6 establishes the Sadguru as the essential 'helmsman' for a devotee's life journey. It posits that whether for spiritual or worldly matters, the boat guided by a Sadguru is the only one that will safely reach the 'far shore.' This guidance goes beyond the material, as the chapter explains that by surrendering with body, speech, and mind to the capable Sai, a devotee can attain the four primary goals of human life—Dharma, Artha, Kama, and Moksha—which are said to come to hand naturally without even asking for them.
