From a devotee's perspective as outlined in Chapter 1, what is the role of the Sadguru, and how is this role fulfilled by Sai Baba?

From the devotee's viewpoint presented in Chapter 1, the Sadguru is the essential guide across the turbulent 'river of worldly existence.' The text explicitly states, 'You alone are our Sadguru, the boat for the river of worldly existence; we are the passengers, show us the other shore.' Sai Baba fulfills this role perfectly. The chapter emphasizes that finding the Sadguru's feet is a great fortune earned through merit from past lives. By identifying Sai with Ganesha (remover of obstacles), Saraswati (giver of knowledge), and the divine trinity, the text portrays him as the all-encompassing, compassionate Sadguru who can lead a devotee to the ultimate 'abode of self-bliss.'
