What was the step-by-step process of communication that eventually cleared up Dev's misunderstanding about Baba not attending his feast?

The misunderstanding was resolved through a three-part communication process involving Dev, Jog, and Sai Baba. As detailed in Chapter 40, the process began when a disappointed Dev wrote a letter to Jog, complaining that Baba had deceived him and failed to appear. Second, Jog took this letter and presented the matter at Sai Baba's feet. Baba then explained to Jog exactly how he had attended in the guise of a Sanyasi with two companions. Finally, Jog, filled with joy, wrote a detailed letter back to Dev, relaying Baba's entire explanation. It was only upon reading Jog's letter that Dev understood the truth, felt deep remorse for doubting Sai, and had his faith restored.
