How does Chapter 42 describe the power and grace of the Sadguru before recounting the story of his passing?

Before detailing the events of Sai Baba's Mahasamadhi, Chapter 42 extols the virtues and power of the Sadguru. It describes Sai as the 'embodiment of Brahman' and the 'Wish-fulfilling Tree (Kalpataru)' for his devotees. The text makes a powerful assertion that 'by the light of the Guru's grace, the distress of the fear of worldly existence is removed' and the 'door to the path of ultimate liberation opens.' As this chapter explains, constantly remembering the Sadguru's feet causes the very nature of obstacles to dissolve, turns unhappiness to happiness, and leads to a state where 'even death shall meet its death.'
