Describe the specific points of confusion and doubt that Dev expressed in his letter to Jog after the Udyapan ceremony.

In his letter to Jog, Dev expressed profound confusion and disappointment. As recounted in Chapter 40, he felt that Baba had deceived him and that His promise to attend had failed. Dev wrote that he had waited with great effort for some spiritual experience but felt nothing had happened. He questioned why, if Baba was to come, he didn't appear in some recognizable guise. Dev lamented, "I don't understand this at all," and stated that if he had been given some proof of Baba's attendance, he would not have felt so let down. The letter clearly shows his belief that Baba had not come and that the assurance he received was not fulfilled.
