From the narrator's perspective, what was so remarkable about the grace Sathe received from Baba after only one week of reading?

The narrator, who was massaging Baba's feet at the time, was filled with wonder and stirred by a powerful thought upon hearing Baba's instruction to Sathe. As mentioned in Chapter 18, the narrator marveled at the apparent ease with which Sathe received such a reward. He thought to himself, 'Baba, how can this be? Sathe gets the fruit with little effort, while years of mine have passed, and he gets the fruit in just seven days!' This highlights the profound and seemingly disproportionate grace Baba bestowed upon Sathe for his one sincere, week-long reading of the Guru Charitra.
