What does Chapter 4 reveal about the divine nature of Sai Baba?

Chapter 4 elevates Sai Baba to the status of the Supreme Divinity. It explicitly states that He who brings joy to the world is the Inner Self and the Supreme God. The text identifies Sai as the Guru and as the Joy-giving Shankar, emphasizing His divine essence. According to Chapter 4, Sai is eternal, non-dual, and beyond all limitations of place, time, or object. His nature is so profound that the four levels of speech cannot describe Him, and even the Vedas, in their attempt, could only resort to saying "Not this, Not this" (Neti-Neti), acknowledging His indescribable and ultimate reality.
