In Chapter 50, the author compares Sai Baba to the sun and the moon. Why are these comparisons ultimately deemed inadequate?

In Chapter 50, the author, Hemadpant, attempts to describe Sai Baba's greatness by comparing him to celestial bodies but finds these analogies lacking. He notes that while Sai can be likened to the sun that dispels the darkness of the world, this comparison is flawed because the physical sun eventually sets. Similarly, if he compares Sai to the moon, the analogy fails because the moon wanes and is not always full. In contrast, the chapter asserts that "Sai is forever complete." This highlights the eternal, unwavering, and complete nature of the Sadguru, whose spiritual light and presence do not diminish or disappear like the sun and moon, making him incomparable.
