What was Sai Baba's initial reaction when Shama brought him Damu Anna's letter, even before its contents were read?

Interestingly, Sai Baba seemed to know the contents of Damu Anna's letter before it was even read to him. As chapter 25 describes, when Madhavrao (Shama) placed the letter at Baba's feet, Baba immediately questioned the plan, asking, 'What does he write? What plans is he making?' He then remarked, 'It seems he is trying to touch the sky! He doesn't want what God gives.' Shama confirmed that Baba's words were the exact meaning of the letter, highlighting Baba's omniscience. Baba then playfully dismissed his own insight, telling Shama to read the letter anyway and not to assume his words were the truth.
