According to the author in Chapter 50, why is it inappropriate to compare Sai Baba to the sun or the moon?

In Chapter 50, the author, Hemadpant, explains the inadequacy of comparing Sai Baba to celestial bodies like the sun and moon. He argues that while these are powerful symbols, they have inherent limitations that Sai transcends. The text explicitly states that comparing Sai to the sun is unfit because the sun eventually sets, implying a period of absence or darkness. Similarly, comparing him to the moon is also flawed because the moon wanes and is not always full. In contrast, Chapter 50 asserts that 'Sai is forever complete.' This comparison serves to highlight Sai's eternal, unchanging, and ever-present nature, which surpasses the cyclical and transient qualities of even the most magnificent objects in nature.
