How does Chapter 4 of the Satcharitra elevate Sai Baba's status from a saint to the Supreme Divinity?

After establishing the general reasons for a saint's incarnation, Chapter 4 transitions to a specific and elevated description of Sai Baba. It equates Him with the Supreme God, the Inner Self who brings joy to the world, and the Joy-giving Shankar. This chapter posits that Sai is the ultimate object of love, eternal and non-dual, existing beyond the limitations of place, time, or object. It further emphasizes His supreme nature by stating that even the Vedas, resorting to the phrase 'Neti-Neti' (Not this, Not this), failed to fully describe Him, illustrating a divinity that transcends all human description and comprehension.
