Chapter 19 begins with several analogies, such as offering water to the ocean. What is the author trying to convey with these examples?

In Chapter 19, the author uses these analogies to express the challenge of describing the indescribable Supreme Reality, which is Sai. The act of writing about Sai is compared to worshipping the sun with a small wick or offering a palmful of water back to the ocean. While these actions may seem small or inadequate when compared to the vastness of the Sun or Ocean, their true value lies in the devotee's faith. The chapter explains that these great powers look at the devotee's faith rather than judging the action, as their goal is to honor the devotee. This illustrates the author's humble attempt to give form and shape to the formless Brahman through devotion.
