Describe the dialogue between Sai Baba and Shama about Damu Anna's letter, focusing on the moments that suggest Baba's omniscience.

The exchange between Sai Baba and Shama, detailed in Chapter 25, strongly suggests Baba's divine foresight. When Shama placed the letter at Baba's feet, Baba asked what plans Damu Anna was making. Even before hearing the contents, Baba stated, 'It seems he is trying to touch the sky! He doesn't want what God gives.' Shama confirmed that this was the exact meaning of the letter, marveling at how Baba could stir devotees' hearts and then draw them close. Shama pointedly asked Baba why He needed the letter read when He already knew its intent. In a humble and playful manner, Baba deflected the compliment, saying, 'I just speak whatever comes to my mind,' before instructing Shama to read it. This interaction showcases Baba's foreknowledge, followed by his characteristic humility.
