Chapter 50 offers several descriptions of Sai Baba's nature. Can you explain why the author finds it difficult to compare him to the sun or the moon?

In Chapter 50, the author, Hemadpant, attempts to describe Sai Baba's divine nature but finds conventional comparisons lacking. He explains that it is not fitting to compare Sai to the sun, because the sun eventually sets, implying a period of absence or darkness. Similarly, comparing Sai to the moon is also inadequate because the moon wanes and is not always full. In contrast, the chapter emphasizes that 'Sai is forever complete,' signifying his constant, unwavering, and perfect nature. This highlights the belief that Sai's presence and grace are eternal and not subject to the cycles of decline or disappearance seen in the natural world.
