Based on Chapter 1, what is the significance of identifying Sai Baba as the 'boat for the river of worldly existence'?

The phrase 'boat for the river of worldly existence' in Chapter 1 is a powerful metaphor for the Sadguru's role in a devotee's life. Just as a boat is essential to safely cross a turbulent river, Sai Baba is presented as the essential guide to navigate the challenges and illusions of 'samsara' or worldly life. The text reinforces this by stating, 'You alone are our Sadguru, the boat for the river of worldly existence; we are the passengers, show us the other shore.' This highlights the belief that with the Guru's grace, devotees can overcome worldly attachments and attain spiritual liberation.
