How did Dev's confusion after hosting the Sanyasi lead him to contact Jog?

After the Sanyasi and his companions had come and gone, Dev was left in a state of profound doubt and disappointment. He felt that he had been promised a visit from Baba but had not received the "experience" he was waiting for. As recounted in Chapter 40, this confusion led him to write a letter to Jog. In the letter, Dev expressed his feeling of being deceived by Baba, questioning why things turned out so differently than expected. He lamented, "How is it that Baba deceived me?" and sought Jog's testimony, hoping for some proof or explanation for why he was left feeling so disappointed despite having served three uninvited guests.
