How does Chapter 19 of the Shri Sai Satcharitra describe Sai's divine nature in relation to the ultimate reality, Brahman?

Chapter 19 presents a profound philosophical discourse equating Sai with the ultimate reality, Brahman. The chapter describes this Brahman as the essence residing in everything, from the smallest atom to the vast universe, being both "subtler than the subtlest and greater than the greatest." The author expresses a desire to give form to this Supreme Reality, using analogies to justify this seemingly paradoxical act. As detailed in chunk 0 of this chapter, just as a devotee offers a small flame in Aarti to the mighty Sun or a jaggery idol to Ganesha, the attempt to describe the indescribable is an act of faith. These great powers look at the devotee's faith, not the logic of the action, because their goal is to honor the devotee.
