According to the text, how is Sai Baba described, and why is he considered beyond comparison to natural phenomena like the sun and moon?

Chapter 50 describes Sai Baba as a direct manifestation of the divine, stating that he is "purely an embodiment of consciousness; the Unmanifest itself has taken form." The author, Hemad, attempts to compare Sai to the sun and the moon but finds these analogies lacking. As explained in Chapter 50, it is not fitting to compare Sai to the sun, because the sun eventually sets, while Sai's presence is eternal. Similarly, comparing him to the moon is inadequate because the moon wanes and waxes, whereas "Sai is forever complete." These comparisons emphasize Sai's eternal, perfect, and unchanging nature, placing him beyond the transient cycles of the natural world.
