What analogies does the author use in Chapter 19 to justify the act of trying to describe the formless Supreme Reality?

In Chapter 19, the author expresses a desire to give form and shape to the Supreme Reality, Sai, who is described as subtler than the subtlest. To justify this seemingly inadequate endeavor, the author provides several analogies. These include a worshipper performing Aarti to the powerful Sun with a small wick, a devotee offering jaggery to a Ganesha idol made from that same jaggery, and offering a palmful of water back to the vast ocean. As explained in Chapter 19, the point of these analogies is that powerful entities like the Sun and the Ocean do not judge the act itself but look at the devotee's faith, seeking only to honor their devotion.
