What metaphors does the author use in Chapter 50 to describe Sai Baba, and why are comparisons to the sun and moon deemed inadequate?

In Chapter 50, the author employs several powerful metaphors, describing Sai Baba as the 'sun that destroys the darkness of the world' and a 'cloud of mercy.' However, the text also carefully explains why even these grand comparisons fall short. As Chapter 50 clarifies, it is not fitting to compare Sai to the sun, because the sun inevitably sets, whereas Sai's presence is constant. Similarly, a comparison to the moon is considered insufficient because the moon wanes and has phases of being incomplete. In contrast, the chapter emphasizes that 'Sai is forever complete,' highlighting his eternal, unwavering, and perfect nature that transcends the cycles of the natural world.
