Describe Sai Baba's reaction when Jog informed him of Dev's letter and feelings of being deceived.

When Jog communicated Dev's feelings of disappointment, Baba reacted with surprise at Dev's inability to see the truth. Chapter 40 states that Baba told Jog to ask Dev, "You did not recognize Me! Why then did you call Me?" He calmly explained that he knows the state of a person's mind even before a letter is opened. He then recounted precisely how he attended the Udyapan as a Sanyasi with two others, emphasizing his unwavering commitment to his promises by declaring, "for the sake of My word, I would die; but the words from My mouth shall never be otherwise." This powerful statement filled Jog with joy.
