Chapter 4 describes Sai as the Supreme Divinity. How does the text explain this concept and the limitations of human understanding in grasping it?

Chapter 4 elevates Sai to the status of the Supreme Divinity, identifying Him as the Inner Self and the Supreme God who brings joy to the world. He is described as the Guru and the Joy-giving Shankar, who is eternal, non-dual, and beyond all limitations of place, time, or object. The chapter emphasizes the inadequacy of human language and intellect to fully comprehend this divinity. It states that the four levels of speech—Para, Pashyanti, Madhyama, and Vaikhari—grow tired trying to describe Him. As mentioned in Chapter 4, even the Vedas, in their attempt to define the indefinable, ultimately resorted to the phrase 'Neti-Neti,' meaning 'Not this, Not this,' acknowledging that the Supreme Reality is beyond all conceptualization.
