How does Chapter 19 describe the nature of Sai and the act of worshipping him?

Chapter 19 explains that Sai is the ultimate reality, Brahman, who resides in everything from the smallest atom to the vast universe, being "subtler than the subtlest and greater than the greatest." The chapter uses analogies to describe worship, comparing it to performing Aarti for the sun with a small wick or offering a palmful of water back to the great ocean. While these acts may seem small, the text emphasizes that powerful entities like the Sun and Ocean look at the devotee's faith, not the scale of the offering, as their goal is simply to honor the devotee.
