Tell me about Kakasaheb Dixit's vision of Vitthal and how Baba confirmed it was real.

The experience of Kakasaheb Dixit, detailed in Chapter 4, is a powerful example of Baba's omniscience. While in meditation after his morning bath, Kakasaheb had a clear vision of Lord Vitthal. Later that day, when he went for Sai Baba's Darshan, Baba immediately and surprisingly asked him, "Vitthal Patil had come, right? Did you meet him?" Baba even playfully warned him to "nail him down and make him steady" because that Vitthal was a "big runaway." The confirmation became even more tangible that afternoon when a seller arrived from out of town with pictures of Vitthal of Pandharpur. To Dixit's amazement, one of the pictures was an exact replica of the form he had seen in his morning vision, proving the authenticity of his experience and Baba's words.
