How did the author react to Sathe's rapid spiritual progress, and how did Sai Baba perceive his inner thoughts?

The author, who was massaging Baba's feet, reacted with a mix of wonder and envy. Chapter 18 reveals his internal monologue where he lamented that Sathe received the 'fruit' of his devotion in just seven days, while his own forty years of reading seemed fruitless. He felt like a 'Chataka bird' waiting for a 'cloud of mercy.' The text emphasizes that Shri Guru Sai, who loves His devotees, immediately knew the thought that arose in the author's mind. It states that Baba has His eye on the millions of good and bad desires that arise and can identify them instantly, demonstrating his omniscience.
