In the beginning of Chapter 19, the author uses examples like offering a jaggery idol to Ganesha or a palmful of water to the ocean. What is the purpose of these opening analogies?

The author begins Chapter 19 with these analogies to justify the humble attempt to describe the indescribable Supreme Reality, personified as Shri Sai. The text mentions a desire to give 'form, color, and shape' to this Reality, which is 'subtler than the subtlest and greater than the greatest.' The author acknowledges that this act might seem inappropriate, much like offering a small wick in Aarti to the magnificent Sun or a palmful of water back to the vast ocean. As explained in Chapter 19, the point is that these powerful entities look at the devotee's faith, not the scale of the offering. Similarly, the author's writing is an act of devotion, whose value lies in the faith behind it.
