How does Chapter 4 philosophically describe Sai Baba as the Supreme Divinity, and what limitations does it say exist in defining Him?

Chapter 4 elevates Sai Baba to the highest spiritual status by identifying Him as the Supreme Divinity, the Inner Self, the Guru, and the joy-giving Shankar. The text uses profound philosophical concepts, describing Him as the object of ultimate love, eternal, and non-dual, existing beyond any division of place, time, or object. It highlights the impossibility of fully comprehending or describing Him, stating that the four levels of speech—Para, Pashyanti, Madhyama, and Vaikhari—get tired in their attempt. As this chapter explains, even the Vedas failed to capture His essence and ultimately resorted to the expression "Neti-Neti," meaning "Not this, Not this," to signify His transcendent and limitless nature.
