How does the author in Chapter 19 justify the worship of a physical form, like an idol or Sai Baba, when the Supreme Reality is formless?

Chapter 19 explains that the desire to give form, color, and shape to the formless Supreme Reality arises from a wish to behold it with physical eyes. The author justifies this practice by emphasizing the devotee's faith over the logic of the act. The text presents analogies, such as performing Aarti to the powerful Sun with a small wick, or offering a palmful of ocean water back to the great ocean. In these examples, the Sun and Ocean do not weigh the right or wrong of the action but look at the devotee's faith, as their goal is to honor the devotee's devotion.
