In what way is Sai Baba described as the Supreme Divinity in the fourth chapter of the Sai Satcharitra?

Chapter 4 elevates Sai Baba to the status of the Supreme Divinity. It explicitly states that He who brings joy to the world is the Inner Self and the Supreme God, identifying this being as the Guru and the Joy-giving Shankar. The text further describes Him as eternal, non-dual, and beyond all limitations of place, time, or object. This chapter emphasizes His transcendent nature by noting that even the four levels of speech get tired of describing Him, and the Vedas ultimately resorted to the phrase 'Neti-Neti' (Not this, Not this), acknowledging that His true form is beyond human comprehension and description.
