How does Chapter 50 describe the fundamental nature of Sai Baba and why is he considered incomparable to celestial bodies like the sun and moon?

Chapter 50 of the Shri Sai Satcharitra delves into the essential nature of Sai Baba, describing him as 'purely an embodiment of consciousness; the Unmanifest itself has taken form.' This suggests that Sai is not merely a human saint but a manifestation of the formless, ultimate reality. The chapter emphasizes his desireless and compassionate state. The author, Hemadpant, attempts to compare Sai to celestial bodies but finds them inadequate. As stated in the text, it is 'not fit to compare him to the sun, for that sun sets,' nor can he be compared to the moon, because 'it wanes.' In contrast, Chapter 50 concludes that 'Sai is forever complete,' highlighting Sai Baba's eternal, unchanging, and perfect nature, which transcends the limitations of the physical world.
