Can you explain the two events that confirmed Kakasaheb Dixit's vision of Vitthal?

Chapter 4 describes two specific proofs that validated Kakasaheb Dixit's vision. The first confirmation came directly from Sai Baba. After Kakasaheb had a vision of Vitthal during his morning meditation, he went to see Baba, who surprisingly asked him, "Vitthal Patil had come, right? Did you meet him?" This demonstrated Baba's omniscience regarding the private spiritual experience. The second proof occurred later that same afternoon when a person from out of town arrived selling pictures of Vitthal. As mentioned in the text, Kakasaheb was amazed to find that the form in one of the pictures was an exact replication of the Vitthal he had seen in his meditation, prompting him to buy it for his personal worship.
