What were the main points of frustration and confusion Dev expressed in his letter to Jog after the Udyapan ceremony?

In his letter to Jog, Dev expressed deep confusion and disappointment regarding Baba's promised visit. The account in Chapter 40 reveals that Dev felt deceived, questioning Baba's words. He lamented that if Jog had also come as expected, it would have served as confirmation. Dev's main frustration was the lack of a clear experience or proof, stating, "I waited with great effort, but no experience came." He could not comprehend why Baba, after telling a devotee who sought refuge that "I am coming," would allow the situation to unfold in such an ambiguous way, leaving him in a state of doubt and disappointment.
