How does Chapter 42 describe the power and effect of a Sadguru's grace on a devotee's life?

Chapter 42 of the Sai Satcharitra beautifully illustrates the profound impact of a Sadguru's grace. It describes Sai as the 'Wish-fulfilling Tree (Kalpataru) for his devotees' causes,' who can show the humble a place at his feet and help them cross the river of worldly existence. The text states that through the 'light of the Guru's grace,' the distress and fear of worldly life are removed, and immediate unhappiness is transformed into happiness. Furthermore, it emphasizes that by 'constantly remembering the Sadguru's feet, the very nature of obstacles dissolves; even death shall meet its death, and the sorrows of worldly life are forgotten,' highlighting the ultimate protection and liberation offered by the Guru.
