In Chapter 50, why does the author find comparisons of Sai Baba to the sun and moon to be inadequate?

In Chapter 50, the author, Hemadpant, attempts to use celestial analogies to describe Sai Baba's greatness but finds them insufficient. He explicitly states that it is not fit to compare Sai to the sun because the sun eventually sets, implying a period of absence or limitation. Likewise, he rejects a comparison to the moon because the moon wanes and is not always full. The core reason for this inadequacy, as stated directly in Chapter 50, is that 'Sai is forever complete.' This highlights the author's belief that Sai's nature is eternal, perfect, and unchanging, transcending the cyclical and impermanent characteristics of even the most magnificent objects in the natural world.
