Who was Jog and what question did he ask Balasaheb Deo in Shirdi?

Jog was a fellow devotee whom Balasaheb Deo encountered in Shirdi. As detailed in Chapter 41, Deo had traveled to Shirdi with his mother and sisters on an auspicious occasion to see the Guru's worship. It was there that Jog approached him and asked a very pointed question: "Why aren't you reading Dnyaneshwari daily these days?" This question was significant because it directly touched upon the central spiritual struggle that had been plaguing Deo, for which he had made a secret and solemn resolve to only read upon a direct command from Sai Baba.
