What was Kakasaheb Dixit's reaction upon seeing Baba's portrait for the first time, and why was this event so significant to him?

When Balasaheb moved the curtain aside from Baba's portrait, Kakasaheb Dixit was overwhelmed with joy and looked at it with a prostration. According to Chapter 51, his eyes were transfixed upon the beautiful and holy photograph. The significance of this moment was the profound coincidence; Dixit longed for Baba's darshan, and right on his way, Baba's very image appeared before him. The fact that the portrait from Shirdi was at Mirikar's house at that exact time made him feel extreme delight, as if Sai himself had orchestrated the event.
