If someone were to ask what Chapter 4 teaches about Sai Baba's divine nature, what key attributes would you highlight from the text?

Chapter 4 of the Sai Satcharitra presents Sai Baba as the Supreme Divinity, and there are several key attributes to highlight. The text describes Him as the Inner Self who brings joy to the whole world, equating Him with God and the Guru. He is defined as the "Joy-giving Shankar," who is eternal, non-dual, and beyond any division of place, time, or object. A crucial point made in this chapter is that His divine nature is beyond human comprehension and description; even the four levels of speech get tired of trying to describe Him, and the Vedas ultimately resorted to saying "Not this, Not this" (Neti-Neti).
