What role did Jog play in the story of Dev's Udyapan ceremony?

In the account from Chapter 40, Jog played the essential role of an intermediary who resolved the misunderstanding between Dev and his perception of Sai Baba. After feeling let down, Dev wrote a letter to Jog in Shirdi, complaining that Baba had not kept His word. Jog then performed the crucial task of communicating the entire account of Dev's feelings at Sai's feet. In response, Baba revealed the truth of the matter. Jog, filled with joy upon hearing Baba's explanation, then wrote a detailed letter back to Dev. This communication from Jog was the catalyst that cleared Dev's delusion, leading him to realize his mistake and feel overwhelming love and remorse for doubting Baba.
