Can you summarize the core message of Chapter 27 regarding faith, devotion, and the Guru's role?

The core message of Chapter 27 is the absolute supremacy of the Sadguru in a devotee's spiritual life. The chapter begins by equating devotion to the Guru's feet with saluting the highest deities and achieving the merit of all pilgrimages. It describes true devotional experience as a profound, visceral reaction—with tears, goosebumps, and a captivated heart—which is evidence of the Guru's grace. This grace is essential, as the text explains that overcoming the six passions and the illusion of Maya is impossible without ultimate faith in the Guru. To escape worldly attachments, one must surrender to Sai with singular devotion, a path that leads to salvation.
