How does Chapter 42 describe the power of a Sadguru's grace and what does it promise to reveal about Sai's personality?

Chapter 42 begins by extolling the virtues of the Sadguru, describing Sai as a 'Wish-fulfilling Tree' (Kalpataru) for his devotees. The text explains that by the light of the Guru's grace, the distress from the fear of worldly existence is removed, and the door to ultimate liberation opens. It states that constantly remembering the Sadguru's feet can dissolve obstacles and even conquer death itself. Furthermore, as mentioned in Chapter 42, the narrative promises to explore Sai's intrinsic nature, posing the question of whether his mind was 'intense or soft,' inviting the reader to understand him on a deeper level before recounting his final departure.
