How does Chapter 4 describe Sai Baba's divine nature, and what does it say about the limits of language in understanding Him?

In Chapter 4, Sai Baba is presented as the Supreme Divinity itself. He is identified as the Inner Self, the Supreme God, the Guru, and the joy-giving Shankar. The text emphasizes that He is eternal, non-dual, and beyond all limitations of time, place, or object. A significant philosophical point made in Chapter 4 is the inadequacy of human language to grasp His true nature. It mentions that the four levels of speech—Para, Pashyanti, Madhyama, and Vaikhari—become exhausted trying to describe Him. Even the Vedas, the highest scriptures, failed in this task and resorted to the expression 'Neti-Neti' (Not this, Not this), signifying that the divine can only be described by what it is not.
