How does Chapter 42 describe the power of a Sadguru and the benefits of remembering them?

Chapter 42 portrays the Sadguru, specifically Sai Baba, as a 'Wish-fulfilling Tree (Kalpataru)' who helps devotees cross the river of worldly existence. The chapter explains that through the Guru's grace, the distress from the fear of this existence is removed, and the door to ultimate liberation opens, turning unhappiness into happiness. As detailed in Chapter 42, by constantly remembering the Sadguru's feet, the very nature of obstacles dissolves, sorrows are forgotten, and even 'death shall meet its death.' The text encourages listening to these stories to attain great holiness.
