How does Chapter 42 explain the significance of a saint's passing and the power of a Sadguru?

Chapter 42 explains that a Sadguru holds the power to guide devotees across the 'river of worldly existence.' It states that by constantly remembering the Sadguru's feet, the very nature of obstacles dissolves, and even 'death shall meet its death.' The chapter elevates the passing of a saint by noting that the 'birth anniversary of gods is the death anniversary (Punya Tithi) of saints,' framing it as a sacred event. It portrays Sai as a 'Wish-fulfilling Tree' (Kalpataru), whose grace removes distress and opens the door to ultimate liberation, which is why, as this chapter suggests, hearing his stories leads to attaining great holiness.
