According to the start of Chapter 42, what is the effect of a Sadguru's grace, and what will this chapter describe?

The beginning of Chapter 42 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 causes obstacles to dissolve and sorrows to be forgotten. Following this explanation, the author promises that Chapter 42 will describe two main things: Sai Baba's nature, exploring whether his mind was intense or soft, and a detailed account of Baba's leaving his physical body, or Mahasamadhi.
