Describe the initial interaction between Sai Baba and Shama when the letter from Damu Anna was presented. What does this reveal about Baba's insight?

The interaction, detailed in Chapter 25, highlights Baba's omniscience. When Shama placed Damu Anna's letter at Baba's feet, Baba immediately commented on its contents without it being read, stating that Damu Anna was "trying to touch the sky" and was not content. Shama confirmed that Baba's words were the exact meaning of the letter. Baba, however, playfully feigned ignorance, saying, "Arre Shama, read it, read it! Why do you think my words are the truth? I am just as I am. I just speak whatever comes to my mind." This exchange shows that Baba already knew the devotee's inner thoughts but engaged in the human act of having the letter read, revealing both his divine insight and his humble, playful nature.
