What is the significance of the Sadguru as described in the first chapter of the text?

The first chapter establishes the supreme importance of the Sadguru, identifying Sainath as the ultimate guide. The text describes the Sadguru as "the boat for the river of worldly existence," with devotees being the passengers in need of guidance to reach "the other shore." As Chapter 1 explains, this relationship is not a matter of chance; the author expresses a firm belief that attaining the Sadguru's feet is a direct result of merit accumulated in past lives. This highlights the idea that the grace of a Sadguru is a profound spiritual attainment, essential for navigating life's challenges and achieving salvation.
