How does Chapter 50 describe Sai Baba's nature, and why is he considered beyond comparison?

Chapter 50 of the Shri Sai Satcharitra beautifully illustrates Sai Baba's divine nature, stating that "Sai is purely an embodiment of consciousness; the Unmanifest itself has taken form." The chapter explains that comparing him to earthly phenomena is inadequate. For instance, the text argues that it's not fitting to compare Sai to the sun, because the sun sets, or to the moon, because the moon wanes. In contrast, as Chapter 50 emphasizes, "Sai is forever complete." This profound description conveys that his being is eternal and unchanging, unlike anything in the material world, making any comparison ultimately fall short.
