According to Chapter 28, what is the nature of a Sadguru like Sai Baba, and how does he interact with his devotees?

Chapter 28 explains that a Sadguru like Sai Baba possesses a unique compassion that transcends a father's role by removing the cycles of birth and death. The chapter highlights His omnipresence, stating that Sai dwells in all beings, from Brahma to the smallest insect. It further details how He interacts with devotees, often appearing in their dreams to guide them. These dream visitations, which could involve asking for khichdi or even disciplinary actions, serve to remove their troubles and addictions, ultimately creating a deep and loving devotion for His feet. This demonstrates the Sadguru's active role in the spiritual upliftment of his followers.
